Answer:
n = 55/8
Step-by-step explanation:

It is a 125% increase from 20 to 45
So probability is (disred outcomes) divided by (total possible outomces
so
hearts and clubs are 2 out of 4 total suits and since there are the same number of cards per suit, it simplifies
2=desrired oucomes
4=total possible
2/4=1/2=0.5=50%
answer is 1/2 or 0.5 or 50%
You just do 12•.65. Then that’s your answer.
