HEY MATE HERE IS YOUR ANSWER
TOTAL NO OF OUTCOMES =20
(i) PROBABILITY OF GETTING 16 = 1/20
(ii) PROBABILITY OF GETTING 14 OR 17 =2/20 =1/10
(iii) PROBABILITY OF GETTING A PRIME NO.=8/20=2/5
(iv) PROBABILITY OF GETTING EVEN NO = 10/20
1/20
(v) PROBABILITY OF GETTING A NO. DIVISIBLE BY 3 = 6/20 =2/10
(vi) PROBABILITY OF GETTING A NO. MULTIPLE OF 5 = 4/20 = 1/5
