→ x = 2.3 ×110÷5 = 50.6 $ Aaron pay
→Brian = 1.1 × 110 ÷5=24.2$
Caleb = 110 - ( 24.2 + 50.6 ) = 110 -74.8 = 35.2$
Answer:
(a) The probability that all three tosses land on heads given that the 1st toss lands on Heads is .
(b) The probability that all three tosses land on heads given that at least one toss lands on heads is .
Step-by-step explanation:
The sample space of tossing 3 coins is:
S = {HHH, HHT, HTH, THH, HTT, THT, TTH, TTT} = 8 outcomes.
(a)
The sample space such that the 1st toss lands on Heads is:
S₁ = {HHH, HHT, HTH, HTT} = 4 outcomes.
The probability that all three tosses land on heads given that the 1st toss lands on Heads is:
P (3 Heads | 1st toss is Heads) =
Thus, the probability that all three tosses land on heads given that the 1st toss lands on Heads is .
(b)
The sample space such that at least one toss lands on heads is:
S₂ = {HHH, HHT, HTH, THH, HTT, THT, TTH} = 7 outcomes
The probability that all three tosses land on heads given that at least one toss lands on heads is,
P (3 Heads | At least 1 Heads)
Thus, the probability that all three tosses land on heads given that at least one toss lands on heads is .
