Correct Answer - Option 2 : 80
Given:
Number of men = 10
Number of women = 8
Concept used:
Number of ways in which one man and woman can be chosen from a group of ‘n’ men and m woman = nC1 × mC1
nCr = n!/[r! × (n – r)!]
Calculation:
Number of ways in which one man and woman can be chosen from a group of 10 men and 8 women = 10C1 × 8C1 = 10 × 8
Number of ways in which one man and woman can be chosen from a group of 10 men and 8 women = 80
∴ The number of ways in which one man and woman can be chosen from a group of 10 men and 8 women is 80
