30, 55, 62, 65, 41.100, 72, and 80 ?

4X5=20​

Answer 1

1. Step-by-step explanation:

a) probability P(E) = no of favourable outcome / total no of outcome

--> no of favourable outcome of selecting A in PROBABILITY = 1

--> total no of outcome = 11

So P(E) = 1 / 11

b) The given numbers are 29 , 28, 30 , 55 , 62 , 65 , 41 , 100 , 72 and 80

Here's the largest value = x(m) = 100 and the smallest value = x(0) = 28

Range = x(m) - x(0)

= 100 - 28

= 72
