Answer:
Most likely the answer is
3x^2+4x-6
Answer:
the probability of inviting both relatives to the meeting = 1/10
Step-by-step explanation:
There are total two invitations that I will send, hence two selections.
For the first selection, I have 5 people total and two of them relatives.
Hence, the probability of inviting relative in first choice is 2/5.
Now assuming that we have invited one relative out of 5 people,
we are left with only 4 people out of which one is relative.
So, probability of inviting relative in second choice is 1/4.
So the probability of inviting both the relatives is (2/5)*(1/4) = 1/10
Each question is either true or false, so the sample space is 2, true and false, two states only.
what's the probability she got one correct, well, the favorable outcomes is 1, possible outcomes is 2, so 1/2.
what's the probability that she got all four correct, we simply multiply the probability of each,
2/5 ≥ x - (4/5). add 4/5 to each side
6/5 ≥ x
