plz help me now

Answer 1

Answer:

(a) 8/15

(b) 6/15 = 2/5

(c) 1/15

(d) 5/15 = 1/3

Step-by-step explanation:

Total Possible Outcome = 15

(a) Odd Numbers between from 1-15 = 1,3,5,7,9,11,13,15

P(getting an odd number) = 8/15

(b) Two digit numbers from 1-15 = 10,11,12,13,14,15

P(getting a two digit number) = 6/15 = 2/5

(c) Multiple of 3 and 5 from 1-15 = 15

P(getting a multiple of 3 and 5) = 1/15

(d) Odd prime number = 3,5,7,11,13 (1 is not a prime number)

P(getting an odd prime number) = 5/15 = 1/3

Hope It Helps Many!!

Have a Nice Day!
