Question

if you pick randomly from 4 card with the numbers 5678 what is the probability that you will get the card numbered 7

Answer 1

1/4

Explanation:

This is an event of 1/4 cards

If events became two different numbered cards with no replacement it would become 1/4 x 1/3 = 1/12

With replacement the odds get larger as there are more cards if picking two specified as random. 1/4 x 1/4 = 1/16

if it was the same number and not replaced it becomes 0/12 as 1/4 x 0/3 = 0/12 = 0

Answer 2

Answer: 25% chance

Explanation:

4 cards total with only one having number 7 on it so choosing one card...

1/4=.25 or 25%

Have a 1 in 4 chance.
