Answer:
Number of ways to satisfy the condition: 10*21 = 210
Step-by-step explanation:
Given:
Total 12 peoples and 4 openings
Including 5 women and 7 men
As the condition suggest that if the exactly two women are selected, so number of ways to select two women out of 5 is
Number of ways to pick 2 women:
5C2 = (5!)/((5-2)!*2!) = 120/12 = 10
Number of ways to pick remaining 2 men:
7C2 = (7!)/((7-2)!*2!) = 5040/240 = 21
As the condition is to select four peoples , it means
Total number of ways to satisfy the problem condition: 10*21 = 210
Answer: 0.27
The events are independent, so we can multiply the probabilities.
P(A n B) = P(A) * P(B)
P(A n B) = 0.3 * 0.9
P(A n B) = 0.27
note: The 'n' represents the "intersection symbol", aka "horseshoe" or "upside down U".
The intersection of two events is like asking when the two events will occur simultaneously. Example: If A represents the event "it rains" and B represents the event "a person won a contest" then P(A n B) represents the probability of it raining and the person winning the contest.
Answer:
B. Commutative Property of Multiplication
Step-by-step explanation:
Commutative Property of Multiplication means that you swap the numbers and get the same answer like 2 x 3 =6 or 3 x 2 =6
According to my examination I have confirmed that I do NOT repeat do NOT know this.
