Problem 3
Disjoint events are two (or more) events that cannot happen at the same time. An example would be flipping heads and tails at the same time with the same coin. Another example is selecting an ace of spades and selecting an ace of diamonds, when you only select one card.
In general notation, P(A and B) = 0 if and only if A and B are disjoint.
P(A or B) = P(A) + P(B) - P(A and B)
P(A or B) = 0.3 + 0.1 - 0
<h3>P(A or B) = 0.4</h3>
=========================================
Problem 5
Same idea, but different numbers
P(A or B) = P(A) + P(B) - P(A and B)
P(A or B) = 1/3 + 1/4 - 0
P(A or B) = 4/12 + 3/12 - 0
<h3>P(A or B) = 7/12</h3>
Answer:
0.21 or 21/100
Step-by-step explanation:
the chance of a female student getting a scholarship is 7/10. now that student already has a scholarship so now there are 9 students. the probability of the next female getting a scholarship is 6/9. and then the next is 5/8
7/10 x 6/9 x 5/8 = 21/100 or 0.21
