1 answer:
Marianna [84]3 years ago
3 0

Answer:

x = 30

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180° , thus

x + 4x + 30 = 180

5x + 30 = 180 ( subtract 30 from both sides )

5x = 150 ( divide both sides by 5 )

x = 30

A die is rolled. Find the probability of the given event.
ozzi

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
