Answer with explanation:</h2>
We know that the binomial theorem for finding the probability of x success out of a total of n experiments is given by:

(a)
b(5; 8, 0.25)
is given by:

Hence, the answer is: 0.023
(b)
b(6; 8, 0.65)
i.e. it is calculated by:

Hence, the answer is: 0.259
(c)
P(3 ≤ X ≤ 5) when n = 7 and p = 0.55

Now,



Hence,

(d)
P(1 ≤ X) when n = 9 and p = 0.1 .613

Also,

i.e.

Hence, we get:

4(2x-5)
the answer to the question
6:3 = 6/3 = 2
13 to 4 = 13:4 = 13/4 = 3.25
19/2 = 9.5
15 to 10 = 15:10 = 15/10 = 1.5
8:2 = 8/2 = 4
From the least to the greatest:
15 to 10 , 6:3, 13 to 4, 19/2
I hope this explains it.
Answer:
5.
Step-by-step explanation:
2[(8−4)5/8]
= 2[4*5 / 8]
= 2 * 2.5
= 5.
