Question

An integer is chosen from 1 to 50 what is the probablity that if it is divasible by 8

Answer 1

Answer:

0.88

Step-by-step explanation:

Integers divisible by 8 between 1 to 100 are the

following No. : 8, 16, 24, 80, 88, 96

This is a Arithmetic Progression, AP, with first term

a= 8, common difference, d= 8, last term, I=96,

number of the terms of the A is, n: where last term, I,

is given by: = a+ (n-1)d

96 = 8 + (n-1) 8 = 8 + 8n - 8

Meaning, number of terms in integers: 1 to 100

divisible by 8, n 96/8 = 12

Number of terms in the integers 1 to 100: not

divisible by 8, n° = 100-12 = 88

Therefore, Probability, Pº, that an integer chosen

between 1 to 100, is not divisible by 8, is given by: P°

= n°/(n° + n) = 88/(12 + 88)

P° = 88/100

pº = 0.88
