Answer:
true
Step-by-step explanation:
it is because 1 and 3 in set A are in sat B
18. P(x then y) = 1/11
19. P(both y) = 5/22
To find the probability of these compound events, we have to multiply the probability of each individual event. Remember, on the second trial, there are only 11 options.
18. 2/12 x 6/11 = 1/11
19. 6/12 x 5/11 = 5/22
Answer:
3.5
Step-by-step explanation:
27/3=9 and 18/3 is 6 so 10.5/3 is 3.5
A(sub2) = 5 * 5^(2-1)
a(sub2) = 5 * 5^1
a(sub2) = 5 * 5
a(sub2) = 25
