Which additional information is needed to solve this problem?
liq [111]
Hi there!

The answer is B.
the cost of the game.

We need to know the cost of the game in order to find out how many weeks John has to save money. If we don't know this price, we'll never know whether John has saved enough money.

We can find out the total amount of money John can save in 1 week (so A. is not the answer). The amount of money John earns per hour doesn't matter to answer the question (so C. is wrong).

~ Hope this helps you!

A fair die is rolled in a board game to determine how many spaces a player can move on their turn. It has one of the numbers 1,2
Jet001 [13]

Answer:

(a)6 (b)3 (c)0.5

Step-by-step explanation:

Given a fair die with the numbers 1,2,3,4,5, or 6 on each of its faces.

  • Event A is the event of rolling an even number
  • Event B is the event of rolling an odd number.

(a)The sample space for the outcomes in this experiment is {1,2,3,4,5,6}

There are <u>6</u><u> </u>outcomes in the sample space.

n(S)=6

(b)

Event A is the event of rolling an even number

Sample space of A = {2,4,6}

There are <u>3</u> outcomes in event A.

n(A)=3

(c)The probability of event A

P(A)=\dfrac{n(A)}{n(S)} =\dfrac{3}{6} =0.5

P(A) =<u>0.5</u> is the probability that you choose an even number.
