Please help fast! Rosa's friend Jake claims that he can read minds. To test Jake's abilities, Rosa chooses 3 different numbers

grigory [225]

Jake's guesses are illustrations of probabilities.

The probability that Jake's guesses are correct is 1/720

The sample size is:

$\mathbf{n = 10}$ --- 10 different numbers

The probability that Jake's guesses are correct is as follows:

1st guess = 1/10
2nd guess = 1/9
3rd guess = 1/8

So, the required probability is:

$\mathbf{Pr = \frac{1}{10} \times \frac 19 \times \frac 18}$

$\mathbf{Pr = \frac{1}{720} }$

Hence, the probability that Jake's guesses are correct is 1/720
