Answer:

75%

Step-by-step explanation:

You pick a card at random. 6 7 8 9 What is P(not 9)? Write your answer as a percentage. %

Given the following

Total cards = 4 (6,7,8,9)

If the card is not 9, the required card will be (6,7,8)

Number of cards that are not 9 is 3

Probability = expected/total

Pr(not 9) = 3/4

express as percent

Pr(not 9) = 3/4×100

Pr(not 9) = 75%

olga_2 [115]

Answer:

3/4 or a 75% chance

Step-by-step explanation:

Out of 4 cards ( 2 3 4 5), here are the cards greater than 3: 4, and 5. That leaves you with a 2/4 chance of drawing one of them. (2 cards, 4 in total).

Then, picking a 4 out of 4 cards is a 1/4 chance; since that is one card out of 4 total possibilities.

1/4 + 2/4 = 3/4. Or, a 75% chance.
