Question

Drag the tiles to the boxes to form correct pairs. Find the probability for the given situations, and then match the situations with the number of times each event is predicted to occur. Josie rolls a six-sided die 18 times. What is the estimated number of times she rolls a two? 3 Slips of paper are numbered 1 through 10. If one slip is drawn and replaced 40 times, how many times should the slip with number 10 appear? 5 A spinner consists of 10 equal- sized spaces: 2 red, 3 black, and 5 white. If the spinner is spun 30 times, how many times should it land on a red space? 6 A card is picked from a standard deck of playing cards 65 times and replaced each time. About how many times would the card drawn be an ace? 4

Answer 1

3-dice

4-slips

5-cards

6-spinner

Explanation:

Answer 2

• 3 (die)
• 4 (slips)
• 6 (spinner)
• 5 (ace)

Explanation:

Josie rolls a six-sided die 18 times. What is the estimated number of times she rolls a two? 3 = (1/6)(18)

Slips of paper are numbered 1 through 10. If one slip is drawn and replaced 40 times, how many times should the slip with number 10 appear? 4 = (1/10)(40)

A spinner consists of 10 equal- sized spaces: 2 red, 3 black, and 5 white. If the spinner is spun 30 times, how many times should it land on a red space? 6 = (2/10)(30)

A card is picked from a standard deck of playing cards 65 times and replaced each time. About how many times would the card drawn be an ace? 5 = (4/52)(65)

_____

The probability of a given event is the number of ways it can occur divided by the number of possibilities. For example, a 2 is one of 6 numbers on a die, so we expect its probability of showing up to be 1/6. The expected number of times it will show up in 18 rolls of the die is (1/6)(18) = 3.
