Galina-37 [17]
For 1. To estimate how many sports cards Alberto had, you would round each number to the nearest ten, so 318 would become 320. 273 would then become 270. You would then add those two and would get 590. So, Alberto had 590 sports cards (estimated). If you were looking for the actual answer (not estimated) , you would get 591.

GaryK [48]

Answer:

2/3

Step-by-step explanation:

A = Student studying Math

B = Student studying Science

P(B|A) = P(A and B) ÷ P(A).

P(B|A) means the probability of event B given event A.

Given :

P(A and B) = 0.40.

Also P(A) = 0.60.

P(B|A) = 0.40 ÷ 0.60 = 2 ÷ 3.

So, the answer is 2/3.
