Answer:

Step-by-step explanation:

given that in a lottery game, a player picks 5 numbers from 1 to 46

If 4 of the 5 numbers match those drawn, the player wins second prize.

Assuming the numbers are chosen without repitition we find that the player can choose 5 numbers in 46C5 ways.

To win the prize he must choose 4 numbers form the 5 numbers in the prize and remaining 1 number any other number.

i.e. no of ways to get II price = choosing 4 numbers out of 5, and one number from 41

= 5C4*41C1 = 205

Probability of winning this prize

=\frac{205}{46C5} \\= \frac{205*5(4)(3)(2)1}{46*45*44*43*42} \\=\frac{41*5*2*3}{46*9*22*43*21} \\=\frac{205}{1370754}

The percentage error is 11.1%

<h3>What is percentage error?</h3>

Percentage error is simply the difference between the exact and the estimated values as a percentage

The given parameters are:

  • Estimate = 45
  • Actual = 50

The percentage error is then calculated as:

\% E = \frac{50 - 45}{45} \times 100\%

Evaluate the difference

\% E = \frac{5}{45} \times 100\%

So, we have:

\% E = \frac{500}{45} \%

\% E = 11.1\%

Hence, the percentage error is 11.1%
