Answer: 1/3
Step-by-step explanation:
Number of red marbles = 5
Number of blue marbles = 9
Number of yellow marbles = 8
Number of and black marbles = 6
Total number of marbles = 28
If Taylor pulled out a yellow one and didn't replce it, there'll be 27 marbles left since one has been removed, then the probability of picking blue marbles will be:
= Number of blue marbles / Total marbles
= 9 / 27
= 1/3
The probability of picking a blue marble is 1/3.

Answer:
0.2700
Step-by-step explanation:
-Notice that this is a binomial distribution with p=0.52, n=4 and x=3.
-The formula for the binomial probabilities is given as:

The probability than in 4, exactly 3 order their food on the go is:

Hence, the probability that exactly 3 order their food on the go is 0.2700
