Question

a group of random people were polled about whether they prefer to communicate using text messages or by phone calls. the results are shown in the conditional relative frequency table by row.

	text	call	total
female	0.46	0.54	1.00
total	0.50	0.50	1.00

what is the probability of someone preferring phone calls, given the person is a female?

• 43%
• 46%
• 54%
• 57%

Explanation:

Step1: Identify the relevant row

We need the probability for females preferring calls, so look at the "Female" row.

Step2: Find the value for "Call" in the "Female" row

In the table, for Female and Call, the value is 0.54. To convert to percentage, multiply by 100: \(0.54\times100 = 54\%\)

Answer:

54% (corresponding to the option "54%")
