If we want to find the probability that both cards are NOT blue, then we are basically finding the probability that both cards are red:

4/10 * 3/9 = 2/15

We did 3/9 because we already took away one red, which we did not replace.

So, the answer is 2/15.

Cerrena [4.2K]

Answer:

28 hours

Step-by-step explanation: you divide 1,456 by 52

52 goes into 145 2 times which is 104, then subtract 104 from 145 to get 41, next bring down the 6 from 1,456 to 41 to make it 416 which 52 goes into 8 perfectly. to make the answer 28

On average, a gym claims that 85% of its members renew their memberships every year. If the gym has 400 members, predict how man
lana [24]

Answer:

340 people would renew their membership if the gym had 400 members

The gym's claim is not accurate, because the prediction should be 340 people instead of 330

Step-by-step explanation:

With 400 members, we can predict how many will renew their membership by multiplying 400 by 0.85:

400(0.85)

= 340

So, this would predict that 340 people would renew their membership.

The gym's claim that 330 members would renew their memberships is not accurate, because the correct prediction should be 340 people.
