Use estimation to select the best response. Do not calculate.

The expectation from playing a game in which you win [tex]$950 by correctly calling heads or tails when you flip a coin is about which of the following?

A. $[/tex]50
B. [tex]$950
C. $[/tex]500


Sagot :

To solve this problem, let's break down the details and the process of estimation.

First, consider the nature of the game. You have a 50% chance of winning [tex]$950 each time you play. Since you're flipping a coin, the probability of either heads or tails occurring is 50%, or 0.5. To estimate the expected value from playing this game, we'll use the formula for expected value: \[ \text{Expected Value} = (\text{Probability of Win}) \times (\text{Win Amount}) \] Here, the probability of winning (flipping heads or tails correctly) is 0.5, and the win amount is $[/tex]950.

Thus, the expected value:
[tex]\[ 0.5 \times 950 = 475 \][/tex]

Rounding to the nearest whole, this is closest to [tex]$500. Therefore, by estimation, the best response would be: $[/tex]500
