Question

Help me please!!!

if the probability of randomly drawing a number ending in 7 is 68/197, what the probability of not drawing a number in 7

Answer 1

total draws is 197 and the probability of getting 7 is 68 so the probability of not drawing 7 is obtained by subtraction of 68 from 197 which is 129 over the total draws or 1-68/197=129/197

Answer 2

129/197

Explanation:

probability = no . of times obtained selecred

event / no. of total out comes in experiment

drawing a number ending in 7 = 68/ 197

not drawing a number in 7 = 197-68/197

=129/197
