Answer:

Because, five can go into 5, 35 and 70. Nothing else bigger can. If we went bigger we would be going over five.

Hope this helps :)

Answer:

a) $P(X=3)=(7C3)(0.38)^3 (1-0.38)^{7-3}=0.28378$

b) $P(X\leq 4) =P(X=0)+P(X=1)+P(X=2) +P(X=3)+P(X=4)$

$P(X=0)=(7C0)(0.38)^0 (1-0.38)^{7-0}=0.0352$

$P(X=1)=(7C1)(0.38)^1 (1-0.38)^{7-1}=0.1511$

$P(X=2)=(7C2)(0.38)^2 (1-0.38)^{7-2}=0.2778$

$P(X=3)=(7C3)(0.38)^3 (1-0.38)^{7-3}=0.28378$

$P(X=4)=(7C4)(0.38)^4 (1-0.38)^{7-4}=0.17393$

And adding we got:

$P(X \leq 4) = 0.92181$

Step-by-step explanation:

Previous concepts

The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".

Solution to the problem

Let X the random variable of interest, on this case we now that:

$X \sim Binom(n=7, p=0.38)$

The probability mass function for the Binomial distribution is given as:

$P(X)=(nCx)(p)^x (1-p)^{n-x}$

Where (nCx) means combinatory and it's given by this formula:

$nCx=\frac{n!}{(n-x)! x!}$

Part a

For this case we want this probability

$P(X=3)$

And using the pmf we got:

$P(X=3)=(7C3)(0.38)^3 (1-0.38)^{7-3}=0.28378$

Part b

$P(X\leq 4) =P(X=0)+P(X=1)+P(X=2) +P(X=3)+P(X=4)$

$P(X=0)=(7C0)(0.38)^0 (1-0.38)^{7-0}=0.0352$

$P(X=1)=(7C1)(0.38)^1 (1-0.38)^{7-1}=0.1511$

$P(X=2)=(7C2)(0.38)^2 (1-0.38)^{7-2}=0.2778$

$P(X=3)=(7C3)(0.38)^3 (1-0.38)^{7-3}=0.28378$

$P(X=4)=(7C4)(0.38)^4 (1-0.38)^{7-4}=0.17393$

And adding we got:

$P(X \leq 4) = 0.92181$
