Final answer:
To find the probability that a statistics course requires an advanced calculator, we can use conditional probability. By multiplying the probability of a course requiring both an advanced calculator and a computer by the probability of just needing an advanced calculator, we can determine the probability. In this case, the probability is 0.4737 or 47.37%.
Step-by-step explanation:
In order to find the probability that a statistics course requires an advanced calculator, we need to utilize conditional probability. We know that 46% of statistics classes require an advanced calculator and 18% of those classes also require the use of a computer.
Therefore, we can find the probability of a statistics course requiring an advanced calculator by multiplying the probability of a statistics course requiring both an advanced calculator and a computer by the probability of a statistics course requiring just an advanced calculator.
P(advanced calculator) = P(advanced calculator and computer) / P(computer)
Given the information, we can substitute the values into the formula:
P(advanced calculator) = 0.18 / 0.38 = 0.4737
The probability that a statistics course requires an advanced calculator is 0.4737 or 47.37%.
