Dulce flipped a coin three times. What is the probability that she will get exactly 2 tails?

For exactly 2 tails, the possible outcome would be 0.38.

Step-by-step explanation:

step 1: Find the total possible combinations of sample space S

S = {HHH, HHT, HTH, HTT, THH, THT, TTH, TTT}

S = 8

step 2: Find the expected or successful events A

A = {HTT, THT, TTH}

A = 3

step 3: Find the probability

P(A) = Successful Events / Total Events of Sample Space

= 3 / 8

= 0.38

P(A) = 0.38

0.38 is the probability of getting exactly 2 Tails in 3 tosses.

Hope this helps :)

step-by-step explanation:

you divide the denominator by the numerator on both sides and if the quotients are equal then the fractions are equivalent
