Answer:
0.167 ; 0.093
Step-by-step explanation:
Given that:
Total number of chocolate squares = 18 of which÷
Number of milk chocolate square = 10
Dark chocolate square = 5
White chocolate square= 3
Probability of choosing a white chocolate square :
Probability = required outcome / Total possible outcomes
Required outcome = white chocolate square = 3
Number of chocolate square = 18
P(choosing a white chocolate square) = 3 / 18 = 1/6 =
B) probability of randomly selecting a milk chocolate first, replace it, and then select a white chocolate?
With replacement :
First pick :
Number milk chocolate = 10
P(choosing a milk chocolate) = 10/18 = 5/9
Second pick:
Number of white chocolate = 3
P(choosing a white chocolate) = 3 / 18 = 1/6
Hence, since both probabilities are independent :
P(choosing milk, then white chocolate) :
(5/9 × 1/6) = 5/54 = 0.0925 = 0.093
