What is the probability of not getting a black ball?

What is the probability of not getting a black ball?

f) not a black ball Therefore the probability of getting not a black ball is 4/5.

What is the probability of both being black?

So, the Prob of both being black is (C10,1/C20,1)*(C10,1/C20,1)= (C10,1)^2/(C20,1)^2 = (10/1)^2 / (20/1)^2 = 100/400 = 1/4.

What is the probability of getting a black ball from a bag having 6 white and 9 black ball?

There are 6 ways to draw a black ball from the bag, out of a total of 9+6=15 ways to draw a ball from the bag. Thus the odds are 6/15.

How do you find the probability of two balls?

So the probability of picking two white balls is (1/6)*0. If the first ball you pick is white, you cannot pick a second white ball. The probability of picking two red balls is (1/3)*(1/5), or (1/15). The probability of picking two black balls is (1/2)*(2/5), or (1/5).

What is the probability of getting tail in a throw of a coin?

When we flip a coin there is always a probability to get a head or a tail is 50 percent. Suppose a coin tossed then we get two possible outcomes either a ‘head’ (H) or a ‘tail’ (T), and it is impossible to predict whether the result of a toss will be a ‘head’ or ‘tail’.

When you draw a card from a pack of 52 cards the probability of drawing a red card is?

In a deck of cards, there are 6 red-faced cards. So, the probability of drawing a red-faced card is 6 out of 52 cards.

What is the probability of Colour being red?

The probability of drawing a red card, P(A) = 26/52 since there are 26 red cards out of the 52 cards in the deck. The probability of drawing a King card, P(B) = 4/52 since there are 4 King cards out of the 52 cards. Now we note that there are red cards that are King cards (King of Hearts and King of Diamonds).

What is the probability of getting a red or white ball?

1 red or a black ball out of 13 can be drawn by 13 C 1 ways Therefore the probability of getting a red ball or a black ball is 13/20. 1 red or a white ball out of 16 can be drawn by 16 C 1 ways Therefore the probability of getting a red ball or a white ball is 4/5.

How many red balls are in a bag of cards?

A bag contains 3 red balls, 5 black balls and 4 white balls. A ball is drawn at random from the bag. What is the probability that the ball drawn is: (i) white (ii) red (iii) black (iv) not red A bag contains 3 red balls, 5 black balls and 4 white balls.

How many red balls can be drawn by 11 non-red balls?

2 red balls out of 11 non-red balls can be drawn by 11 C 2 ways Let D be the event of getting exactly one red ball i.e. one red and 1 non red ball 2 red balls out of 11 non-red balls can be drawn by 11 C 2 ways ∴ n (D) = 9 C 1 x 11 C 1 = 9 x 11 Therefore the probability of getting exactly one red ball is 99/190.

What is the difference between bag 2 and BAG 3?

Bag II contains Bag I contains 1 white, 2 black and 3 red balls; Bag II contains 2 white, 1 black and 1 red balls; Bag III contains 4 white, 3 black and 2 red balls. A bag is chosen at random and two balls are drawn from it with replacement.
