Answer:
Step-by-step explanation: if you want to obtain the probability that x<em> </em>
-3 , then you need to add the probability for the cases x=-3 and x=-5.
p=0.13+0.17= 0.3
answer=0.3
.25+ .2 +.5= .95 so cousins cards make up 5% so 30 cards is half of that so that make 30 cards 2.5%. So 2.5 x 40 = 100% and 30 x 40=1200..... So Steve has 1200 baseball cards......
Hopefully I'm right... it just feels like it too much cards...;)
