⏳ You select a marble without looking and then put it back. If you do this 11 times, what is the best prediction possible for the number of times you will pick a green marble?

• There are 11 marbles. There are 11 possible outcomes.

2 of marbles are green . There are 2 favorable outcome.

The Probability is 2 out of 11 ,or 2/11.

Now Find 2 / 11 of 11.

2 / 11 *11 = 2

⏳ You select a marble without looking and then put it back. If you do this 11 times, what is the best prediction possible for the number of times you will pick a blue marble?

• There are 11 marbles. There are 11 possible outcomes.

5 of marbles are blue . There are 5 favorable outcome.

The Probability is 5 out of 11 ,or 5/11.

Now Find 5 / 11 of 11.

2 / 11 *11 = 2

The best prediction possible is 5 out of 11 times.

• There are 2 possible outcomes: heads or tails.
• There is 1 favorable outcome: tails.
• The probability is 1 out of 2, or1/2.
• Now find 1/2 of 12.
• 1/2× 12 = 6
• The best prediction possible is 6 out of 12 times.
