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

klasskru [66]

9514 1404 393

Answer:

  N = 5; only one rate is possible

Step-by-step explanation:

The values of the sets of chips are ...

  12 +9N +8N^2 +4N^3

and

  2 +N +N^3 +N^4

We want to find N such that the difference in value is zero:

  N^4 -3N^3 -8N^2 -8N -10 = 0

A graphing calculator can show us the roots. There is only one positive real root to this equation: N = 5.

The exchange rate N is 5. Only one rate is possible.
