Amonth of the year is selected at random. what is the probability that it has 31 days or starts with the letter j

1/6

Step-by-step explanation:

January and July both have 31 days in them so that makes 2/12 months and 2/12 simplified is 1/6

It is 2/12 because there are 12 months in a year and only 3 of the start with j but only 2 of the have 31 days

1/6

Step-by-step explanation:

(a) 0.610 or 61%

(b) 0.390 or 39%

Step-by-step explanation:

(a) The total number of people who received a degree in this year to choose from is 795,325; the number of women within the total population is 485,142. Therefore, the probability that the chosen person is female is:

[tex]P(F)=\frac{485,142}{795,325}=0.610\ or\ 61\%[/tex]

(b) Assuming that students are either male or female, the probability of the selected student being male is:

[tex]P(M) = 1- P(F)=1-0.610=0.390\ or\ 39\%[/tex]
