(a)0.64

(b)0.48

(c)0.3072

(d)0.76

Step-by-step explanation:

Domestic Equity funds= 16

Funds rated 3-star or less=13

Domestic Equity fund were rated 4-star=7

Domestic Equity funds were rated 5-star=2

Total Sample of Funds taken=25

Domestic Equity Funds+International Equity=25

16+International Equity Funds=25

International Equity or Fixed Income Funds =9

For, Domestic Equity Funds (16)

Funds Rated 5 Stars = 2

Funds Rated 4 Stars=7

Therefore, Funds Rated 3 Stars=16-9=7

Since 13 mutual funds were rated 3 Stars or less,

Domestic Equity Funds Rated 3 Stars + International Equity Rated 3 Stars =13

7+International Equity Rated 3 Stars=13

International Equity Rated 3 Stars=13-7=6

International Equity or Fixed Income(9)

Rated 3 Stars=6

Rated 4 or 5 Stars=9-6=3

(a)Probability of selecting a Domestic Equity Fund

Number of Domestic Equity Funds=16

Total Sample of Funds=25

P(selecting a Domestic Equity Fund) = =0.64

(b)Probability of selecting a fund with a 4 or 5-star rating.

International Equity Rated 4 or 5 Stars=3

Domestic Equity Funds Funds Rated 4 or 5 Stars = 2+7=9

Total Funds Rated 4 or 5 Stars=3+9=12

Therefore:

P(selecting a fund with a 4 or 5-star rating)==0.48

(c)Probability of selecting a fund that is both a Domestic Equity Fund and a fund with a 4 or 5-star rating.

Number of Domestic Equity Funds=16

Total Funds Rated 4 or 5 Stars=12

P(Domestic Equity Fund AND a fund with a 4 or 5-star rating)

= =0.3072

(d)Probability of selecting a fund that is a Domestic Equity Fund or a fund with a 4 or 5-star rating.

Note:

P(A or B)= P(A)+P(B)-P(A AND B)

Number if Domestic Equity Funds rated 4 or 5 Stars=9

= =0.76
