Bello chooses a number randomly from 1 to 10. What is the probability that it is either odd or prime?

A. \(\frac{1}{10}\)
B. \(\frac{2}{5}\)
C. \(\frac{1}{2}\)
D. \(\frac{3}{5}\)
E. \(\frac{9}{10}\)

the numbers from 1,2,3,4,5,6,7,8,9,10. n( total numbers) = 10

the odd numbers are 1, 3, 5, 7, 9 n( odd) = 5

the prime numbers are 2, 3, 5, 7 n( prime) = 4

but total favourable outcome = ( 1,2,3,5,7,9) = 6

Pro( odd or prime no) = \(\frac{6}{10}\) = \(\frac{3}{5}\)
