An unfair coin with Pr[H] = 0.75 is flipped. If the flip results in a head, a student is selected at random from a class of six boys and sixteen girls. Otherwise, a student from a different class containing five boys and six girls is selected. What is the probability of selecting a girl, given the flip resulted inheads?

72.73% probability of selecting a girl, given the flip resulted inheads

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

Coin resulted in heads

Student is selected at random from a class of six boys and sixteen girls.

Desired outcomes:

16 girls, so

Total outcomes:

16+6 = 22, that is, 22 students, so

Probability:

72.73% probability of selecting a girl, given the flip resulted inheads

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.

25 questions , because they start with 100.  

350-100=250 .  

. 250/10=25

step-by-step explanation:

first take off 100, then what x 10 = 250? that is your answer. (25)
