# What is the probability that a randomly selected senator is a Democrat and up for reelection in November 2016?

The probability is $0.15$

See the step by step solution

## Step 1: introduction

Probability is just the way that probably something is to occur. At the point when we're uncertain about the result of an occasion, we can discuss the probabilities of specific results — how likely they are. The investigation of occasions administered by likelihood is called insights.

## Step 2: explanation

The probability that a randomly selected senator is a Democrat and up for reelection in November $2016$= No. of candidates up for reelection in nov $2016$/ Total no. of candidates

Hence the probability is = $\frac{10}{67}=0.15$
