Question

Matrix is handing out treats at a local protest to promote his new detective agency. He allows each participant to reach into his bag of goodies and select a treat. Then he replaces it with the same treat and shakes the bag before offering a treat to another person. Matrix’s bag bag of goodies contains the treats below. If he allows 40 people to choose a treat from the bag, about how many lizard lollies can he expect to give away

Answer 1

Answer:

20 lizard lollies

Step-by-step explanation:

I attached the missing data.

Given the quantity of each treat below,

Swordfish sockers = 4

Lizard lollies = 10

Puffer pops = 6

From the figures above, the total number of treats is =

4 + 10 + 6 = 20

Since Martrix allows each participant to reach into his bag of goodies and select a treat, he then replaces it with the same treat and shakes the bag before offering a treat to another person. The probability a person picks lizard lollies will be:

Number of lizard lollies / total number of treats

$\frac{10}{20} = \frac{1}{2}$

Since the probability a person picks lizard lolllies is ½, If he then allows 40 people to choose a treat from the bag, the number of lizard lollies he can expect to give away will be:

½ * 40 = 20 lizard lollies
