The probability is0.5625.

Step by step solution

01

Given information 

Given in the question that, In the Japanese game show Sushi Roulette, the contestant spins a large wheel that鈥檚 divided into 12 equal sections. Nine of the sections have a sushi roll, and three have a 鈥渨asabi bomb.鈥� When the wheel stops, the contestant must eat whatever food is on that section. To win the game, the contestant must eat one wasabi bomb .

02

Explanation 

Given:

Number of trials (x)=3

Number of events (n)=12

Probability of success is:

p=xn

=312

=0.25

The probability of getting a wasabi bomb after three or more spins is determined as follows:

P(X鈮�3)=1鈭�[P(X=1)+P(X=2)]

=0.5625

The deck of 52cards contains 13hearts. Here is another wager: Draw one card at random from the deck. If the card drawn is a heart, you win 2. Otherwise, you lose 1. Compare this wager (call it Wager 2) with that of the previous exercise (call it Wager 1). Which one should you prefer?

(a) Wager 1, because it has a higher expected value.

(b) Wager 2, because it has a higher expected value.

(c) Wager 1, because it has a higher probability of winning.

(d) Wager 2, because it has a higher probability of winning. (e) Both wagers are equally favorable
