Question

a restaurant hands out a scratch - off game ticket with prizes being worth purchases at the restaurant. the back of the ticket lists the probabilities of winning each dollar value: 0.05 for $25, 0.04 for $50, 0.02 for $75, and 0.01 for $100. what is the probability that the ticket is worth at least $75?

Explanation:

Step1: Identify relevant prizes

The prizes that are at least $75$ are $75$ and $100$.

Step2: Sum their probabilities

The probability for $75$ is $0.01$ and for $100$ is $0.0001$.
$$0.01 + 0.0001$$

Step3: Calculate the sum

$$0.01+0.0001 = 0.0101$$

Answer:

$0.0101$
