Content Introduction

There are two events:

C = Californians (registered voters) preferring life in prison without parole over the death penalty for a person convicted of first degree murder.

L = Latino Californians.

02

Content Explanation

Given that,

P(C)=0.48P(L)=0.376

Therefore,

P(L鈥�OR鈥�C)=P(L)鈥�+P(C)-P(LAND鈥�C)=0.376+0.48-0.207=0.649
