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:

x = 1

y = 3

Step-by-step explanation:

2x + 1 = y ------- eqn (1)

2y = 6--------eqn (2)

from eqn(2)

2y = 6

y = 3

when you divide 6 by 2y

substitute y = 3 into eqn (1)

2x + 1 = y

2x + 1 = 3

2x = 3-1

2x = 2

therefore

x = 1
