Answer:
No correlation
Step-by-step explanation:
There is not a positive line of dots
There is not a negative line of dots
so that means there is no correlation
Answer:
Option C.
Domain:
{3, 0, 2, 4}
Step-by-step explanation:
The domain is the set of all the values of x.
Answer:
a) the probability of winning A and B is 0.4 (40%)
b) the probability of not winning either project is 0.1 (10%)
Step-by-step explanation:
if 2 events are independent then
P(A∩B)=P(A)*P(B)
where
P(A)= probability of winning project A
P(B)= probability of winning project B
P(A∩B)= probability of winning projects A and B
replacing values
P(A∩B)=P(A)*P(B) = 0.50 * 0.8 = 0.4
b) since
P(A∪B) = P(A) + P(B) - P(A∩B) = 0.50 + 0.8 - 0.4 = 0.9
where
P(A∪B) = probability of winning A or B
therefore
probability of not winning either project = 1 - P(A∪B) = 1 - 0.9 = 0.1 (10%)
Answer:
156 different pairs will be there.
Step-by-step explanation:
As the order is essential as we need different pairs therefore permutations will be used.
A permutation is any ordered subset of the objects r selected with regard to their order, from the set of n distinct objects. It is given by nPr where n> r
Total number is 13 and required number is 2
n= 13 and r= 2
13 P2= 156 possible combinations.
A combination is any subset of the objects r selected without regard to their order, from the set of n distinct objects. It is given by nCr where n> r
