Answer: The probability that 7 of these seeds will germinate when 10 are planted is 0.1298 .
Step-by-step explanation:
Let x be the number of seeds germinate .
Since each seed is independent from other , so we can use binomial over here.
Binomial probability formula : , where n= total trails and p is the probability of each success.
As per given : p= 0.85 , n= 10
Then, the probability that 7 of these seeds will germinate when 10 are planted will be :-
Hence, the probability that 7 of these seeds will germinate when 10 are planted is 0.1298 .
For this case we must find an expression equivalent to:
By definition of power properties we have to meet:
Then, we can rewrite the expression as:
