Question

if n(A) =2 and n(A) =36 find p(A)​

Answer 1

Answer:

n(A)=90

Step-by-step explanation:

Let n(A) be x

P(A)=n(A)/n(s)

5/2 = x/36

36 x 5/2 = x

18 x 5 = x

90 = x

Answer 2

n(A) = 90

Step-by-step explanation:

Given Data

n (s) = 36

P(A)=\frac{5}{2}P(A)=25

To find n(A)

Probability is defined as the ratio between number of possibilities and total number of given items.

P(A)=\frac{n(A)}{n(S)}P(A)=n(S)n(A)

Substitute the respective values in the above equation

\frac{5}{2}=\frac{n(A)}{36}25=36n(A)

\frac{5 \times 36}{2}= n(A)25×36=n(A)

n (A) = \frac{180}{2}n(A)=2180

n (A) = 90

Therefore if the total number n(S) is 36 and probability p(A) is \frac{5}{2}25  then their number possibilities n(A) is 90
