What is the probability that all four balls are blue?
The required probability of drawing 4 blue balls is 7/66.
What is the probability of selecting 4 balls from a bag?
This probability is 4/10=0.4.
What is the probability of red balls?
a) a red ball Therefore the probability of getting a red ball is 9/20. Therefore the probability of getting a white ball is 7/20.
What is the probability of picking a red ball for the first time on the fourth attempt?
The probability to pick the first time a red ball is obviously 1/4=0.25.
How do you find the probability of two bags?
The probability of choosing ‘bag 1′ is 1/2. Similarly, probability of choosing ‘bag 2′ is 1/2. Probability of picking up a red ball from ‘bag 1’ = 6/16. Probability of choosing a red ball from ‘bag 2′ = 4/10.
What is the probability that you pick four red balls?
The probability that you pick four red balls is Since you have to pick 4 balls, the number of elements in the sample space would be 11 C 4 (“11 choose 4”). The number of ways of picking all red balls would be 6 C 4.
How to find the probability of two balls of the same color?
The two balls are of the same color if X = 0 or 2, and of different colors if X = 1. You can get the numerical values of the probabilities by evaluating the ‘binomial coefficients’, or by using software. In R statistical software the computation is as follows: Ignore the row numbers in brackets.
How many red and blue balls are in a bag?
A bag contains 3 red balls and 4 blue balls. Find the probability of picking at random two balls of a) the same color b)different colors [closed] Closed. This question needs details or clarity.
How many ways can the 4 red balls be arranged?
The 4 red balls an be arranged in 4! ways. The 4 red balls leave 3 gaps between them and the two extreme sides i.e. 5 places to insert the 3 yellow and the 2 green balls. These can be arranged in 5! ways.
