Question

Determine the probability of an event whose odds against are partial differential to 1. A) p (E) = 1/4 B) p (E) = 1/3 C) p (E) = 1/3 D) p (E) = 1/partial differential E) p (E) = 3/4 You are dealt one card from a standard 5 partial differential car Calculate the probability that you are a five or a black card. A) 1/partial differential B) 15/partial differential C) 30/5 g D) 0.partial differential 5 E) 7/13 A political discussion group consist of 30 partial differential 5, 8 independents, and 4 of the party. If one person is chosen at random from the group, determine the probability of crossing an Independent or a Green. These events are ______ so the probability is ______ A) Mutually exclusive: 34/67 B) Independent: 1 partial C) differential/67 D) mutually exclusive; 34/67 E) Independent; 34/67

Explanation / Answer

Q1.

the odds against the event are 2 : 1
The outcomes against the event 2
The outcomes for the event : 1
Total number of outcomes : 2+1=3
Probability for the event : 1/3
Probability against the event: 2/3

Q2

Favroable number of cases to draw a card from 52 cards is 52C1 = 52

No of cases to draw one card numbered 5 = 4C1 = 4

No of cases to draw one black card = 26C1 =26

Prob = (4+26)/52 = 30/52

Q3.

Mutually Excluisve, 12/67

Probability = (8C1+4C1)/67C1 = 12/67
