Answer:
20
Explanation:
She has 5 types of candies
and 4 types of chocolates
If she randomly selects 1 chocolate ; she has 4 different options
then she selects 1 candy ; she has 5 different options
Therefore, she has 4 x 5 = 20 options
But, how ?
chocolates are => a,b,c,d
candies are => 1,2,3,4,5
she can select
(a,1)(a,2)(a,3)(a,4)(a,5) => 5 options
(b,1)(b,2)(b,3)(b,4)(b,5) => 5 options
(c,1)(c,2)(c,3)(c,4)(c,5) => 5 options
(d,1)(d,2)(d,3)(d,4)(d,5) => 5 options
therefore, 5 x 4 = 20 options
Hope this helps ^-^
