Question

there are boards number 1 to 50 in the box one box is selected at random find the probability that the number on the box is 1)multiple of 11 and 2)prime number 3)multiple of 10​

Answer 1

Step-by-step explanation:

1. multiples of 11 are 11,22,33,44. so probability is 4/50
2. prime numbers are 2,3,5,7,11,13,17,23,29,31,37,41,43,47

so probability is 14/50

3. multiples of 10 are 10,20,30,40,50

so probability is 5/50

hope this will help u

Answer 2

Answer:

Total no. of outcomes =50

1) Favourable outcomes =11,22,33,44

=4

P (multiple of 11)=4/50

=2/25

2) Favourable outcomes=2,3,5,7,11,13,17,19,23,29,31,37,41,43,47

=15

P (prime number)=15/50

=3/25

3) Favourable outcomes=10,20,30,40,50

=5

P (multiple of 10)=5/50

=1/10
