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 :-
![P(X=7)=^{10}C_7(0.85)^7(1-0.85)^3\\\\=\dfrac{10!}{7!3!}(0.85)^7(0.15)^3\\\\=0.129833720754\approx0.1298](https://tex.z-dn.net/?f=P%28X%3D7%29%3D%5E%7B10%7DC_7%280.85%29%5E7%281-0.85%29%5E3%5C%5C%5C%5C%3D%5Cdfrac%7B10%21%7D%7B7%213%21%7D%280.85%29%5E7%280.15%29%5E3%5C%5C%5C%5C%3D0.129833720754%5Capprox0.1298)
Hence, the probability that 7 of these seeds will germinate when 10 are planted is 0.1298 .
