(PlS anSwER aSaP!) I'LL GIVE BRAINLY TOO THE FIRST ANSWER!!!!

Answer 1

The probability that she picked a card that is not red is 11/14

Step-by-step explanation:

Number of blue marbles n(blue)=4

Number of red marbles n(red)=3

number of yellow marbles n(yellow)= 2

number of green marbles n(green)=5

total number of marbles n(S)=4+3+2+5=14

P(red)=n(red)/n(S)

P(red)=3/14

We have to determine the probability that the card picked is not red which means the card can be blue or yellow or green.

P(not red)=1-P(red)

                =1-3/14

                 =11/14
