What is the probability of picking a number 6 from numbers one to 15 in 99 trials?
Prob(Pick 6 from 1-15 in 99 trials) = 1 - Prob(Don't pick 6 from 1-15 in 99 trials) = 1 - (14/15)99 = 1 - (0.933...)99 = 1 - 0.00108 approx = 0.9989

A bag contains 4 red marbles and 5 blue marbles If two marbles are chosen at random what is the probability of getting two red marbles?
1/6Because:There is a 4 in 9 chance of picking a red ball the first time and 3 in 8 chance of picking a red ball the second time. The chance of picking two reds as the first two balls is 4/9 x 3/8 or 12/72 or 1/6

A two-digit whole number is randomly selected What is the probability that it is an odd multiple of 3?
The event space comprises the numbers 10 to 99, 90 such numbers. The favourable events are 15, 21, 27, ... , 99. There are 15 such numbers. So the probability is 15/90 = 1/6

3/5 probability of a white ball being drawn.
A bag contain 4 green 6 black 7 white balls a ball is drawn at random what is the probability that it is a green or a black ball?
This is a law of addition probability which states that the probability of A or B equals the probability of A plus the probability of B minus the probability of A and B. Written in mathematical terms, the equation is: P(AorB) = P(A) + P(B) - P(AnB) where P(AnB) = 0 (since you can not pull out a green and black ball at the same time). Let P(A) = Probability of drawing the green ball & let P(B) = Probability of drawing the black ball. Total outcomes is 17. So, P(A) = 4/17 & P(B) = 6/17. Therefore P(green or black) = 4/17 + 6/17 = 10/17.
