Question

Numbers from 1 to 50 are written on a piece of paper and dropped into a box. A paper is chosen at random a. Find the probability of choosing either multiple of 4 or multiple of 5.

Answer 1

The total no. of outcomes=50

Let A be the event of getting a multiple of 4 or 5.

Then favourable outcomes = 12+10=22

Then P(A)=22/50=11/25

Answer 2

Answer:

The probability is 11/25.

Step-by-step explanation:

Sample of possible outcomes = {$1, 2, 3, 4, 5, .\ .\ .\ , 46, 47, 48, 49, 50$}

Total number of possible outcomes = 50

Multiples of number 4 = {$4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48$}

So, total number of multiples of 4 = 12

Multiples of number 5 = {$5, 10, 15, 20, 25, 30, 35, 40, 45, 50$}

So, total number of multiples of 4 = 10

Thus,

Number of favorable outcomes,

= Total no. of multiples of 4 + Total no. of multiples of 4

= 12 + 10

= 22

Probability of choosing either multiple of $4$ or multiple of $5$,

= (Number of favorable outcomes)/(Possible outcomes)

P(choosing either multiple of $4$ or multiple of $5$) = $\frac{22}{50}$

                                                                               = $\frac{11}{25}$

Therefore, probability is 11/25.
