Answer:
the second one.
Step-by-step explanation:
(8+4:2)-1*3=(8+2)-1*3=10-1*3=10-3=7;
(8+4):2-1*3=12:2-1*3=6-1*3=6-3=3.
Answer:
1/16
Step-by-step explanation:
first we find the probability of picking a 2 and then a 5 , then we multiply the two probabilities
probability of picking a 2 on the first time is 1/4 as there is 1 2 and 4 total cards.
the probability of picking a 5 is also 1/4 as there is 1 5 and 4 total cards
so the probability of picking a 2 and then a 5 would be 1/4 * 1/4 = 1/16
