Question
Attempts: A bucket contains N- 11 tickets with different scores. Let X be the outoome of a random draw from this bucket. The graph below shows the frequency distribution histogram for these scores. FREQUENCY 3 0 5 The table below shows the probability distribution for X x Value 2. 3 5 Pex) Suppose you take a random sample of one score from this buc 3) that this score shows a number greater tang isplxs3) take a random sample of one score from this bucket. The probability that this score shows e 31s .r The probability umber less than 3 is p(x 3)- The probabil ty that this score shows a n
Explanation / Answer
P(X=3)=2/11
P(X<3)=P(X=1)+P(X=2)=3/11 +2/11=5/11
P(X>3)=P(X=4)+P(X=5)=3/11+1/11=4/11
