Ross has a fourth of the amount needed to buy a new computer. The computer cost ($213 divided by 55) divided by 4. Show how you could calculate the amount of money ross has?

The amount of money that Ross has = $0.97

Step-by-step explanation:

We are told in the question that Ross has a fourth of the Amount needed to buy his computer.

Let us represent cost of the computer as = Y

Hence, Ross has = 1/4 of Y

From the question, we are told the cost of the Computer. Therefore,

Y = $213÷ 55

Y = $3.8727272727 = $3.87

The cost of the computer = $3.8727272727

Since Ross has 1/4 of the amount needed for the computer ,

This is calculated as : 1/4 × $3.8727272727

=$0.9681818182

Approximately: $0.97

Therefore, The amount of money that Ross has = $0.97

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.
