Janitor · Answer 1

Step-by-step explanation:

Step 1: Determine if Gareth is correct

Total number of cards → 10 + 4 → 14

Probability of choosing lower → 4/14 → 2/7

Probability of choosing higher → 10/14 → 5/7

Since 5/7 > 2/7, that means that Gareth is correct be choosing a higher card.

Answer: Yes

Carly · Answer 2

Yes

Step-by-step explanation:

There are total 10+4 = 14 cards

P (higher than 5) = 10/14 = 5/7

P (lower than 5) = 4/14 = 2/7

There's a higher chance of the card being greater than 5
