Suppose you have a bag with 20 letter tiles in it and 7 of the tiles are the letter Upper Y. If you pick a letter tile at rando

KonstantinChe [14]

Answer:

Step-by-step explanation:

Probability is expressed as

Number of favorable outcomes/number of total outcomes

Considering the first bag, the probability that you pick a letter that is Upper Y is 7/20 = 0.35

Converting to percentage, it becomes

0.35 × 100 = 35%

Considering the second bag, the probability that you pick a letter that is Upper Y is 240/500 = 0.48

Converting to percentage, it becomes

0.48 × 100 = 48%

Therefore, you are more likely to pick a tile that is the Upper Y letter from the second bag.
