Rachel’s free-throw average for basketball is 60%. Describe how you can use 10 index cards to model this situation. Then use a s
Thepotemich [5.8K]

1. If Rachel's free-throw percentage is 60%, you can take 4 index cards away since 100 - 40 = 60%. For example, if those 10 index cards represent 10 free-throws, and her percentage is 60%, just take 60 away from the total (100%).

2. For the simulation, it's the same as problem 1. Since 50 is the total amount of shots she is going to take, and you know she is going make 60% of them, take 60% from 50 which gives you 30. That means she will make 30 of them and miss 20 of them

The probability of event A is 0. 48, the probability of event A and B is 0. 21, and the probability of events A or B is 0. 89. W
Mice21 [21]

Probabilities are used to determine the chances of an event

The probability of event B is 0.62

The probabilities are given as:

\mathbf{P(A) = 0.48}

\mathbf{P(A\ and\ B) = 0.21}

\mathbf{P(A\ or\ B) = 0.89}

To calculate the probability of event B, we make use of the following formula

\mathbf{P(A\ and\ B) = P(A) + P(B) - P(A\ or\ B)}

So, we have:

\mathbf{0.21 = 0.48 + P(B) - 0.89}

Collect like terms

\mathbf{P(B)= -0.48  +0.21 + 0.89}

\mathbf{P(B)= 0.62}

Hence, the probability of event B is 0.62
