(a) The number showing is a 4; The probability is :
(b) The number showing is an even number; The probability is :
(c) The number showing is greater than 5; The probability is

Answer 1

Answer:

(a) 0.1666 (b) 0.5 (c) 0.166

Step-by-step explanation:

A die is rolled so sample space = { 1,2,3,4,5,6 } so n=6

(a) the number showing is four so expected value is only 4 so favorable outcomes {4}

so probability $P=\frac{1}{6}=0.1666$

(b) the number showing an even number

so favorable outcomes= { 2,4 ,6 }

so probability $P=\frac{3}{6}=0.5$

(c) the number showing greater than 5 that is only {6}

so probability $P=\frac{1}{6}=0.1666$
