Four of the cards have an even number, so the probability of drawing an even is \dfrac48=\dfrac12.

Only two cards have a number greater than 6 (7 and 8), so the probability of drawing one of them is \dfrac28=\dfrac14.

The probability of both events happening is

\dfrac12\times\dfrac14=\dfrac18

oee [108]

Answer:

A- b: the y value when y changes; the point where a line crosses the v-axis

B- m: What happens to y when x is one; the ratio of the y change to the x change

C- k: The y value when x is zero b x increases by one

Step-by-step explanation:

If this is about slope intercept form as i think it is

C sounds a little bonkers in this case though because when y is zero then x increases by one

You toss 3 coins what is the probability that you get exactly 2 heads given that you get at least one tail
forsale [732]
Seeing as there are three coins, which means there are 3 heads and 3 tails.There's only a 50% chance it'll land on either side one one coin. I believe the chances to get two heads, and one tail would be somewhere around 80%, since there are only 8 possible outcomes.
