Aswim team consists of 7 boys and 6 girls. a relay team of 4 swimmers is chosen at random from the team members. what is the probability that there are 2 boys on the relay team given that there are 2 girls on the relay team? express your answer as a fraction in lowest terms or a decimal rounded to the nearest millionth.

21/55

Step-by-step explanation:

Since there are already 2 girls on the relay team, what is left is to select 2 individuals be it a girl or a boy from the remaining 7 boys and 4 boys.

This can be done in 11C2 ways, and this equal 55 ways.

Now, we were told that we want exactly 2 boys on the team to join the other 2 girls already on the team. This mean we select 2 boys from the 7 boys. This can be done in 7C2 ways and this equals 21 ways.

Our probability is now 21/55

answer: when you burn wood, the carbon reacts with the oxygen in the air to create ash and smoke. that is a permanent change you cannot undo that.

step-by-step explanation:

c

step-by-step explanation:

there is vertical asymptote at x = 2 and x = 0

vertical asymptote occurs at the points where the denominator is 0. so we can say that

x = 2 occurs when there is a factor (x-2) in the denominator, and

x = 0 occurs when there is a factor "x" in the denominator

thus, the denominator of the equation would have "x * (x-2)", this is option c only. that's the correct answer.
