FinnZ [79.3K]

Answer:

15 hours

Step-by-step explanation:

$x$ is the number of hours that Liam volunteered in the first month

The next month he volunteered $1\dfrac{2}{3}$ times the time he volunteered the first month.

Total time he volunteered in the two months is 40 hours so

$x+1\dfrac{2}{3}x=40\\\Rightarrow x+\dfrac{5}{3}x=40\\\Rightarrow \dfrac{3x+5x}{3}=40\\\Rightarrow x=\dfrac{40\times 3}{8}\\\Rightarrow x=15$

Time he volunteered in the first month is 15 hours.

Three cards are drawn from an ordinary deck without replacement. Find the probability that all three are Hearts.

shepuryov [24]

Answer:

11/850 or about 1.29%.

Step-by-step explanation:

Prob ( first drawn = heart) = 13/52 = 1/4.

Prob ( second drawn = heart) = 12/51 = 4/17.

Prob ( third drawn = heart) = 11/50.

Required probability = 1/4 * 4/17 * 11/50

= 11/850.
