Answer:
No, he is wrong
Step-by-step explanation:
To find that probability, the first thing we need to know is the total number of coins present.
Mathematically, that would be 3 + 2 + 3 = 8
Since there are 8 coins, the probability of selecting a dime is number of dimes/total number of coins = 2/8 = 1/4
The probability we want to work with is that the two selections are dimes, let’s say with replacement.
That means; first selection is a dime and second selection is also a dime
Mathematically in probability, the term and means that we have to multiply our results.
So the probability that both are dimes would be 1/4 * 1/4 = 1/16
And this makes his answer wrong

1. 1m=100 cm
1m^2= 10,000 cm^2
2. if 3 pencils are 1.65, then 1 pencil is 1.65/3=$ 0.55
7 pencils will cost 7* $0.55= $3.85
3.1 ha is 10,000 m^2, and 1 soccer filed is roughly 100m *110 m
so it makes sense that 1 ha is roughly 2 tennis courts
4.odd numbers between 20 and 30 are
21,23,25,27,29
lets add the,m
21+23+25+27+29=125
5 a rhombus has 2 lines of symmetry
