Answer:
The answer is 6 and -6
Step-by-step explanation:
The given equation is
where a = 1. b = -k, c = a
since the equation (1) has equal roots
Hence volume of k = 6, -6
Answer:
we have
Step-by-step explanation:
considering circle with 100 points on it and then placing the wolf on one and sheep on rest.
pi = P( sheep on i-th spot is eaten at last}
As in the question we need to find probability of sheep opposite to the wolf, so p_{51}. observe each last spot is replaced by i-1 after eating
Byy LOTP we know thta
also these pi need to satisfy
some sheep is eaten at last. Distribution is
satisfies above equation, therefore we have
The answer is <em>X</em>= 15/19
Let BS be the event that the patient survives bypass surgery.
Let H be the event that the heart damage will heal.
Then P(BS) = 0.60, and also we have a conditional probability: GIVEN that the patient survives,
the probability that the heart damage will heal is 0.5, that is P(H|BS) = 0.5
We want to know P(BS and H).
Using the formula of the conditional probability:
P(H and BS) = P(H|BS)·P(BS) = (0.6)(0.5) = 0.3
