49. From 3 coin tosses, there are 8 possible outcomes:

... TTT, TTH, THT, THH, HTT, HTH, HHT, HHH

All but the first have at least one head, so 7/8 of the possibilities have at least one head. That's 87.5% (not among your choices).

Likewise, all but the last listed outcome have at least one tail. The problem is symmetrical that way when the coin is fair. 87.5% of outcomes have at least one tail.

___

Perhaps you can tell I read your question as having two parts. If your question is the probability of getting at least one head AND at least one tail, you can see that condition includes 6 of the 8 outcomes, or 75%, matching selection d.

50. See for yourself: the calculator says 66.82%. Your best choice is selection d.

Step-by-step explanation:

3. The tree increased in height each month until the time period between month 9 and month 11.

Step-by-step explanation:

We have been given a table that shows the height of the tree that Margo planted over an 11-month period.

Let us see which of the given statement can be supported by the information in the table.

1. The tree increased in height each month during the entire 11-month period.

We can see from our table of data that Margo's tree increased till 9 months and its height decreased between 9 to 11 months from 3 feet to 1.8 feet, therefore, first statement is not true.

2. The tree decreased in height each month during the entire 11-month period.

We can see from our table that height of Margo's tree increased till 9 months from 1.4 feet to 3 feet and its height decreased between 9 to 11 months from 3 feet to 1.8 feet, therefore, second statement is not true.

3. The tree increased in height each month until the time period between month 9 and month 11.

We can see that height of tree increased for 9 months (1.4 ft to 3 ft) and between 9 to 11 months height decreased (3 ft to 1.8 ft), therefore, our 3rd statement is true and the information given in the table is supporting this statement.

4. The tree decreased in height each month until the time period between month 9 and month 11.

We have seen that the tree increased in height each month until the time period between month 9 and month 11, therefore, our 4th statement is not true.
