Answer:
20 games.
Step-by-step explanation:
Given:
Meredith is playing games at an arcade to earn tickets that she can exchange for a prize.
She has 255 tickets from a previous visit.
She earns 6 tickets for each game she plays.
Meredith needs 375 tickets to exchange for the prize she wants.
Question asked:
How many games does Meredith need to play?
Solution:
Total tickets needed to exchange for the prize = 375
Meredith already have = 255 tickets
More tickets needed = 375 - 255 = 120 tickets

She earns 6 tickets by playing = 1 game
She earns 1 ticket by playing = game
She earns 120 tickets by playing =
Therefore, she needs to play 20 games to earn 120 more tickets.
Answer:
The correct option is 4) 0.72.
Step-by-step explanation:
Consider the provided information.
Let us consider that there are 100 members.
(Note: you can take any number the answer will remain the same.)
90% of its members drank protein shakes and of the members who drank protein shakes.
90% of 100 is 90.
Thus, 90 members drank protein shake.
Of the members who drank protein shakes, 30% took weight-loss medication.
30% of 90 is 27.
That means 27 out of 90 took weight loss medication.
Out of 100 members 90 drank protein shakes that means 10 members does not take protein shakes.
Only 10% of members who did not drink protein shakes took weight-loss medication.
10% of 10 is 1, that means 1 member out of 10 took weight loss medication.
Thus the required table is:
Medication Not Medication Total
Drank shakes 27 63 90
Doesn't Drank shakes 1 9 10
Total 28 72 100
Now we need to find the probability that a gym member does not take weight-loss medication.
72 out of 100 members does not take weight-loss medication.
Therefore, the required probability is:
Hence, the correct option is 4) 0.72.
