Practice JKCET Probability Distribution in the app →If a fair coin is tossed twice and $X$ = number of heads, then $P[X = 1]$ equals:In the experiment of tossing two fair coins, let $X$ be the number of heads. Then the probability distributionUsing the same distribution as above ($P[X=0]=0.1$, $k=0.15$), $P[X < 2]$ equals:If two cards are drawn with replacement from a deck of 52, $P[X = 2]$ where $X$ = number of aces equals:A fair die is thrown. Let $X$ = number of factors of the number on the upper face. $P[X = 2]$ equals:The probability distribution of the **number of doublets** in three throws of a pair of dice is:
