Question

1. Abigail plays a game in which she spins a spinner over and over again. The spinner has 4 equally sized sections labeled 1 through 4. Spinning a 2 eight times means the game is over.
Abigail uses a uniform probability model to predict the number of times the spinner will be spun before the number 2 appears 8 times.

What is Abigail's prediction for the number of total spins before the number 2 appears 8 times?


32 spins

16 spins

8 spins

4 spins

2. A computer is used to generate passwords made up of numbers 0 through 9 and uppercase letters. The computer generates 500 passwords one character at a time.

A uniform probability model is used to predict the first character in the password.

What is the prediction for the number of passwords in which the first character is a number?

Round your answer to the nearest whole number.


69 passwords

139 passwords

192 passwords

292 passwords

3. Samuel uses a uniform probability model for an experiment using a deck of 30 cards. There are 6 blue cards, 6 red cards, 6 green cards, 6 yellow cards, and 6 brown cards in the deck. Cards will be drawn one at a time and then replaced in the deck before another card is drawn.

He uses the probability model to determine the probability of drawing a yellow card or a blue card.

What is P(yellow or blue)?
