The probability that a randomly selected American was not in support of the bill was

Answer 1

Step 1

The total number of Americans from the poll who opposed the bill where 449 and 258 were not sure.

The total number of Americans in the poll = 1000

Probability is defined as;

`Pr(event)=\frac{number\text{ of required events}}{Total\text{ number of events}}`

Number of required events= Those not in support of the bill = 449+258=707

Total number of events= 1000

Hence the probability that a randomly selected American was not in support of the bill was

`Pr(not\text{ in support of bill\rparen=}(707)/(1000)=0.707`
