(Round to three decimal places as needed.) d) The probability of randomly selecting an executive who earned between $70,000 and $90,000 per year is __. (Round to three decimal places as needed.)Explanation / Answer
Solution:-
a) Of the executive at this organisation, 1 earned $ 100, 000 or more per year.
b) The probability of randomly selecting an executive who earned $ 100,000 or more year is 0.034.
Number of executive at the organisation, who earns $ 100, 000 or more per year = 1
Total number of executive = 29
The probability of randomly selecting an executive who earned $ 100,000 or more year is 0.034.
c) The probability of randomly selecting an executive who earned $60,000 or more year is 0.828.
Number of executive who earned $60,000 or more year = 24
Total number of executive = 29
The probability of randomly selecting an executive who earned $60,000 or more year is 0.828.
d) The probability of randomly selecting an executuive who earned between $70,000 and $90,000 per year is 0.448.
Number of executuive who earned between $70,000 and $90,000 per year = 8 + 5 = 13
Total number of executive = 29
The probability of randomly selecting an executuive who earned between $70,000 and $90,000 per year = 13/29 = 0.448
