Atechnician is launching fireworks near the end of a show. of the 14 remaining fireworks, nineare blue and five are red. if she launches six of them in a random order, what is the probability that exactly 4 of them are blue ones?

0.3268

Step-by-step explanation:

Given : The number of fireworks are blue = 9

Total remaining = 14

Probability of choosing blue ones

Using binomial probability formula ,

, where p is the probability of success in each trial, n is sample size.

If she launches six of them in a random order then n=6.

The probability that exactly 4 of them are blue ones will be :-

Hence, the required probability = 0.3268

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11 -1> 1 -1+ a

-12 > a
