Are these the correct answers?

1. A large department store sells sport shirts in five sizes (small, medium, large, xlarge, & xxlarge), and three patterns (plaid, print, and stripe). The following table gives the sales count for a recent month.

Country Plaid Print Stripe
Small 15 7 7
Medium 30 25 44
Large 12 27 30
XLarge 32 18 11
XXLarge 18 7 17

(a) (3) If a shirt is randomly selected, what is the probability that it is striped?
7+44+30+11+17=109
15+30+12+32+18+7+25+27+18+7+7+44+30+11+17=300
109/300=0.3633
(0.3633)(100)=36.33%
(b) (3) If a shirt is randomly selected, what is the probability that it is xxlarge?
18+7+17=42
42/300= 0.14
(0.14)(100)=14.00%
(c) (3) If a shirt is randomly selected, what is the probability that it is a small plaid?
15/300=0.05
(0.05)(100)=5.00%
(d) (3) If a striped shirt is randomly selected, what is the probability that it is a medium?
7+44+30+11+17=109
44/109=0.4037
(0.4037)(100)=40.37%
(e) (3) If a large shirt was randomly selected, what is the probability that it is a print?
12+27+30=69
27/69=0.3913
(0.3913)(100)=39.13%
