Question 9 20% of a particular brand of light bulbs fail in one year. What is the probability that three bulbs out of a random collection of 8 bulbs fail in one year

The correct answer is 0.15

Step-by-step explanation:

According to the given scenario, the probability is as follows:

X Bin (n,p)

Here

n = 8

p = 0.20 or 20%

Now this is a binomial probability distribution

= 0.15

Hence, the correct answer is 0.15

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.
