Question

Find the probability distribution of number of doublets in three throws of a pair of dice

Answer 1

if two dice are thrown ,there are 6×6=36outcomes . doublets means that it means same number is obtained on both throw of die. no of doublets possible on two throws of die are (1,1),(2,2),(3,3),(4,4),(5,5),(6,6). then p(getting a doublet )=6/36= 1/6. then p(not getting doublets)=1_1/6=5/6
