Answer:6/7
Step-by-step explanation:
so basically given observation is u got a tail from a biased coin.
so our favorable case is getting a tail from biased coin.
we will use the probability for it:
p1= probability of getting choosing biased coin and getting tail =probability of choosing biased coin* probability of tail = 3/4*1
p2= probability of choosing a fair coin and getting tail= probability of choosing fair coin*probability of getting tail on it = 1/4*1/2 = 1/8
so p(E)= p1/(p1+p2)= 3/4/(3/4+1/8)=7/8
Answer:
4x^2 + 12x + 9
Step-by-step explanation:
(2x + 3)^2
it is in the form of (a + b)^2
(a + b)^2 = a^2 + 2*a*b + b^2
(2x + 3)^2
(2x)^2 + 2*2x*3 + (3)^2
4x^2 + 12x + 9
