desired
hmm,

there are 50 numbers in the range from 1 to 50

half the numbers from 1 to 50 are divisiblle by 2
sothat leasves all the odd numbers

the odd multilules of 7 are, 7, 21, 35, 49
the odd mulitpules of 9 are 27, 45

there are  6 more tobe minused

25-6=19
19/50 is the proababltity o
which is 38%
