Answer :
Sure! Here is the step-by-step solution for the given problem:
We are asked to find the probability of winning no more than 8 times out of 10 plays of an arcade game.
1. Understand the type of distribution: Since the game can either be a win or a loss and each play is an independent event, this scenario follows a binomial distribution. In a binomial distribution, we denote:
- [tex]\( n \)[/tex] as the number of trials (in this case, 10),
- [tex]\( p \)[/tex] as the probability of success (winning the game), given as 0.632,
- [tex]\( k \)[/tex] as the number of successful trials we are interested in (no more than 8 in this case).
2. Set up the problem: We need to calculate the cumulative probability of winning 0 to 8 times out of 10, which is represented as [tex]\( P(X \leq 8) \)[/tex].
3. Calculate the cumulative probability:
To find this probability, we use the cumulative distribution function (CDF) for the binomial distribution. The CDF sums up the probabilities of all outcomes from [tex]\( k = 0 \)[/tex] to [tex]\( k = 8 \)[/tex].
4. Result: Using the cumulative distribution function for the binomial distribution with [tex]\( n = 10 \)[/tex], [tex]\( p = 0.632 \)[/tex], and [tex]\( k \leq 8 \)[/tex], the probability [tex]\( P(X \leq 8) \)[/tex] is:
[tex]\[ P(X \leq 8) = 0.9306 \][/tex]
So, the probability of winning no more than 8 times out of 10 plays of the arcade game is approximately [tex]\( 0.9306 \)[/tex] or [tex]\( 93.06\% \)[/tex].
I hope this explanation helps you understand how to approach and solve binomial probability problems! If you have any more questions, feel free to ask!
