Rolling Dice Roll two standard dice and add the numbers. What is the probability of getting a number larger than 9 for the first

Rudik [331]

Answer:

$\frac{1}{6}$

Step-by-step explanation:

The sum is larger than 9, it means we have: 10, 11, and 12

To get the outcome is 12, we have only one way is that the two dice shows face-6. The probability to have 12 is:

P(12) = $\frac{1}{6} *\frac{1}{6}$ = $\frac{1}{36}$

To get 11, we have it two ways once dice shows face-5 and the other shows face-6 and vice versa

P(11) = 2* $\frac{1}{6} *\frac{1}{6}$ = $\frac{1}{18}$

To get 10, we have it three ways ( once dice shows face-5 and the other shows face-6 and vice versa , two dice show 5)

P(10) = 3* $\frac{1}{6} *\frac{1}{6}$ = $\frac{1}{12}$

So the probability of getting a number larger than 9 for the first time on the third roll is:

P(12) + P(11) +P(10 )

= $\frac{1}{36}$ + $\frac{1}{18}$ + $\frac{1}{12}$ = $\frac{1}{6}$

For a school field trip the students had two options for lunch, a turkey or egg salad sandwich, so it is impossible for a studen

Allisa [31]

Answer: 0.77

Step-by-step explanation:

Given : Probability that a student chooses a turkey sandwich is

P(Turkey )= 0.10

Probability that a student chooses an egg salad sandwich is

P(egg salad)=0.67

Also, it is impossible for a student have both lunches.

∴ P(Turkey and egg salad) =0

Now , the probability that a student chooses a turkey or egg salad sandwich will be

P(Turkey or egg salad) = P(Turkey )+ P(egg salad)- P(Turkey and egg salad)

= 0.10+ 0.67-0 = 0.77

Hence, the probability that a student chooses a turkey or egg salad sandwich= 0.77
