Question

Из тридцати выпускников шестеро поступили в МАИ, восемь человек-в МАДИ, четверо-в МГУ, а остальные пошли работать. Какова вероятность, что случайно выбранный выпускник работает?

Answer 1

30-(6+8+4)=12 выпускников пошли работать

т.е. вероятность, что случайно выбранный ученик работает 12/30= 2/5,если нужно перевести в десятичную дробь, то 0,4=40 процентов.

Answer 2

Probability of a randomly chosen graduate working

To calculate the probability of a randomly chosen graduate working, we need to determine the number of graduates who went to work out of the total number of graduates.

According to the given information, out of 30 graduates: - 6 went to MAI (Moscow Aviation Institute)- 8 went to MADI (Moscow Automobile and Road Construction Institute)- 4 went to MGU (Moscow State University)- The rest went to work

To find the number of graduates who went to work, we subtract the number of graduates who went to the three mentioned institutions from the total number of graduates:

30 - (6 + 8 + 4) = 12

Therefore, 12 graduates went to work.

To calculate the probability, we divide the number of graduates who went to work by the total number of graduates:

Probability of a randomly chosen graduate working = Number of graduates who went to work / Total number of graduates = 12 / 30 = 0.4 or 40%
