matt and ruba each have one coin.
The total amount of money is less than 50p.
work out the probability that exactly one of the coins is a 10p piece.
assume that all possible coins are equally likely.
what's p?
do the coins come in 1p by 1p or 10p by 10p? Not too sure about the coin system.
the 50p is a 50p piece it says in the book it is less than 50p (money)
sorry...... no idea. I mean it could be 49p, 49.99p, 49.999999p...?
Do they come in whole numbers or what.
To find the probability that exactly one of the coins is a 10p piece, we need to find the total number of possible outcomes and the number of favorable outcomes where exactly one of the coins is a 10p piece.
Let's determine the total number of possible outcomes first. Since Matt and Ruba each have one coin, and the total amount of money is less than 50p, there are four possibilities for the coins' values:
1. Both coins are less than 10p.
2. One coin is 10p and the other is less than 10p.
3. One coin is less than 10p and the other is 10p.
4. Both coins are 10p.
Now let's count the favorable outcomes, where exactly one of the coins is a 10p piece. From the four possibilities, we see that there are two favorable outcomes:
1. One coin is 10p, and the other is less than 10p.
2. One coin is less than 10p, and the other is 10p.
Therefore, the probability of exactly one of the coins being a 10p piece is 2 out of 4, or 2/4. Simplifying, we get 1/2 or 0.5.
So, the probability that exactly one of the coins is a 10p piece is 0.5 or 50%.
