Question 1 of 8

No calculator

A discrete random variable X is described by this table

The event is \(6\le X\le 10\)

Find the probability of the stated event

(a)1 mark

Which set lists exactly the values that satisfy \(6\le X\le 10\)?

\varnothing

\{4, 6\}

\{6, 10\}

\{4\}

(b)1 mark

Which expression correctly combines the probabilities of the event values?

1-(\frac{1}{8} + \frac{1}{2})

\frac{1}{8} \times \frac{1}{2}

\frac{1}{8} + \frac{1}{2}

\frac{\frac{1}{8} + \frac{1}{2}}{2}

Complete the probabilities for the values in the event

\(\Pr(X = 6)\) \(\Pr(X = 10)\)

(d)1 mark

Find the probability of the stated event. Give the answer as an exact probability
