Tickets to a baseball game cost $12 for adults and $7 for children. how much will tickets cost for 3 adults and 4 children?

So total cost of tickets = $64

Step-by-step explanation:

Given:

Cost of adult = $12

Cost of Children = $7

Total Adults = 3

Total children = 4

To Find:

Total Cost = ?

Solution:

We are given per person price and no of persons too now

Total cost = Cost of children ticket + Cost of Adults ticket

Now we will find the values

Cost of 3 adults ticket = total person * cost per person

                                     = 3 * 12

                                     =$36

Cost of 4 Children ticket = total person * cost per person

                                     = 4 * 7

                                     =$28

Now

Total cost = Cost of children ticket + Cost of Adults ticket

putting value

Total cost = 28 + 36

                 = $ 64

So total cost of tickets = $64

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
