(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
