Answer:
4.25
Step-by-step explanation:
-x^2 + 3x + 2 = 0
Divide by -1
X^2 -3x - 2 = 0
x^2-3x+ =2+2.25
(x-1.25)-4.25
(x-1.5)
Answer:
robability formula is the ratio of number of favorable outcomes to the total number of possible outcomes. Measures the likelihood of an event in the following way: - If P(A) > P(B) then event A is more likely to occur than event B. - If P(A) = P(B) then events A and B are equally likely to occur.

Given :
The probability of someone having a reaction to a medication is 0.025 .
To Find :
The probability of two out of tree people having a reaction.
Solution :
Let, P is the probability of two out of tree people having a reaction.
So, P = ( first had reaction ) × ( second had reaction ) × ( third do not had reaction )
P = 0.025 × 0.025 × ( 1 - 0.025 )
P = 0.00061
Hence, this is the required solution.
