We have the formula (sin x)^2 + (cos x)^2 = 1;
Then, sin α =
cos β =
We apply the formula sin ( α + β ) = sin α x cos β + sin β x cos α = (3/5)x(4/5) + (4/5)x(3/5) = 12/25 + 12/25 = 24/25;
Then, sin α =
cos β =
We apply the formula sin ( α + β ) = sin α x cos β + sin β x cos α = (3/5)x(4/5) + (4/5)x(3/5) = 12/25 + 12/25 = 24/25;
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 .
