Total marbles = 10+4 = 14
prob of green marble = 10/14 = .71
Then if you are getting 2 green marbles you have to first take out 1 green marble so now there are 9 green marbles and 13 total green marbles
prob of 2nd green marble = 9/13 = .69
So you would then multiply the probabilities of the individual events to get the total probability:
.71 * .69 = .4899 therefore(with rounding):
The probability of getting two green marbles is 49%
Answer:
C
Step-by-step explanation:
Simplify 4.3^2-7?
= 4 × 3^2 - 7
= 4 × 9 - 7
= 36 - 7
= 29
Answer is B because what it is asking you to do is which ones are about 50% so you add the percents from the answers together and the one that isn't close to 50% Is the answer this is B because
32+29+13=74 this is the only one that is way to big if you add the others they are approximately 50%
= 80%
