Question

I need a well explained answer




A number is selected from

the 1rst 50 natural numbers.

Find the probability that the number selected is

prime.​

Answer 1

so the number is in between 1 to 50

so the number can be

1 2 3 4 5 6 7 8 9 0

11 12 13 14 15 16 17 18 19 20

21 22 23 24 25 26 27 28 29 30

31 32 33 34 35 36 37 38 39 40

41 42 43 44 45 46 47 48 49 50

the prime numbers are = 2 3 5 7 11 13 17 19 23 29 31 37 41 43 47

probability = fav outcome / total outcome

number of prime number = 15

the total outcome = 50

p = 15/50

= 3/10
