The diver’s depth is 18.5 feet below from sea level.
Given that, A diver begins at sea level and dives down 200 feet.
He ascends at a steady rate of 121/3 feet per minute for 4.5 minutes.
This depth is represented by the numerical expression is,
Negative sign indicate that below the sea level.
Hence, The diver’s depth is 18.5 feet below from sea level.
Answer:
a) X={BBB;BBG:BGG:GGG}
b) P(BBB)=0.125
c) P(BBB)=0.133
Step-by-step explanation:
The sample space states all the possible values that the random variable can take. In this case, the order does not matter, so the possible combinations for the random variable are:
X={BBB;BBG:BGG:GGG}
The probability p of having a boy is p=0.5, as it is equally likely to have a girl or a boy.
The probability that all 3 children are boys can be calculated multiplying 3 times the probability of having a boy. That is:
In the case that the chance of having a boy is p'=0.51, the probabiltity of having 3 boys become:
