Harry Potter drove 30 miles in 75 hours. At this rate, how long will it take

vova2212 [387]

first you will need to find his speed = 0.4 mph (that's really slow, idk if i was wrong)

next up, it will take him about: 40 ÷ 0.4 = 100 hours for him to drive 40 miles

Three coins are dropped on a table.

Dominik [7]

Answer:

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

(b) $\frac{1}{8}$

(d) $(\frac{1}{2})^3 + \binom{3}{1} (\frac{1}{2})^3 = \frac{1}{8} + \frac{3}{8} = \frac{1}{2}$

(e) $1 - \frac{1}{2} = \frac{1}{2}$

(f) Yes, because $P(A \cap B) = 0$ . Therefore $P(A \cup B) = P(A) + P(B) = \frac{3}{8} + \frac{1}{2} = \frac{7}{8}$

(g) No, because $P(A \cap C) = \frac{3}{8}$ . Therefore $P(A \cup C) = P(A) + P(C) - P(A \cap C) = \frac{3}{8} + \frac{1}{2} - \frac{3}{8} = \frac{1}{2}$

Amount spent by Chloe = $43

Amount left after Chloe's spending = $0
