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
Step-by-step explanation:
cross product. Ise the butrerfly or cross and bones method. Multiply -4 and 49. Put that in the numerator. Then multiply 7 and 16. Put that in the denominator. Then reduce if u can.
They must have the same variable with the same exponent. The coefficient doesn't matter much.
