The probability that exactly 1 doesn't grow will be 0.07
<h3> What is Probability?</h3>
It is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
We can use Bernoulli estimation to solve this. P(g) = 0.85, probability of not growing into healthy plant P(n) = 1-P(g) = 1 - 0.85 = 0.15
Using the Bernoulli approximation:
P(n=1)=⁹C₁xP(n)¹.⁵xP(g)⁸.⁵
P(n=1)=9x0.15¹.⁵x0.8⁸.⁵
P(n=1)=0.07
Hence the probability that exactly 1 doesn't grow will be 0.07

Karan swam and biked for a total of 1 hour and 45 minutes.
let's say 60=100 for a total of 100 equaling 1 hour.
Therefore, 100+45= <u>145</u>
Answer: 193.8125
8 pairs cost 221.50
1 pair costs 221.50/8
7 pairs cost 221.50/8 * 7 which is 193.8125
