Tyler selects one card from the three(4,5, and a King), and rolls a number cube. What is the probability that she selects the 5,
Svet_ta [14]

\frac{1}{3}Answer:

2/9

Step-by-step explanation:

given that Tyler selects one card from the three(4,5, and a King), and rolls a number cube.

We find that A the event of selecting one card and B getting a number on rolling a number cube are independent events.

No of cards = 3

Prob of selecting 5 from 3 cards = P(1,2,3, or 4) = \frac{2}{3}

When rolling a number cube (assuming fair) there is equally likely for all numbers to appear from 1 to 6

Prob of getting 5 =\frac{1}{6}

Prob of getting less than 5 =

Since these two events are independent,

the probability that she selects the 5, and rolls a number less than 5

= Product of probabilities

= \frac{1}{3}*\frac{2}{3}

=\frac{2}{9}

-4x + 7y = 9  ⇒ -4x + 7y = 9  ⇒     8x - 14y = -18
2y = -5x - 22 ⇒ -5x - 2y = 22 ⇒ <u>-35x - 14y = 154</u>

Your friend rolled a number cube and got number 5. On his next turn he says he won’t be able to get another 5 because his chance
Sophie [7]

Answer:

he can still get a 5 but he is equally likely to get any other number 1 to 6

Step-by-step explanation:

he has a 1/6 chance of rolling 5 the first turn and it becomes more and more rare to roll lots of 5s in a row

1/6

1/36

1/216

etc

each time the denominator is multiplied by 6 because it is less likely he will roll a 5 so many times in a row
