The Reds and the Cubs are playing 3 games. In each game the probability that the Reds win is 0.54. The probability of the Reds w

shusha [124]

Answer:

(a) 1.6197

(b) 1.3803

Step-by-step explanation:

(a) Let X denote the number of games the Reds win. If Reds win exactly one it means that in the other two games Reds lost i.e Cubs won. Now, the probability of the Reds losing is determined by $1 -\text{probability of winning} = 1-0.54 = 0.46$ . So, if X wins exactly $i$ times, then we should multiply the probabilities associated with

$P(X=0) = \binom{3}{0} \times 0.46 \times 0.46 \times 0.46 = 0.0973$

$P(X=1) = \binom{3}{1} 0.54 \times 0.46 \times 0.46 = 0.3429$

$P(X=2) = \binom{3}{2} 0.54 \times 0.54 \times 0.46 = 0.4023$

$P(X=3) = \binom{3}{3} 0.54 \times 0.54 \times 0.54 = 0.1574$

Now,

$E(X) = \sum_{i=0}^{3} i \times P(X=i) = 1.6197$

(b) Let Y denote the number of games won by Cubs. Then by the similar logic as above,

$P(Y=3) = \binom{3}{0} 0.46 \times 0.46 \times 0.46 = 0.0973$

$P(Y=2) = \binom{3}{1} 0.54 \times 0.46 \times 0.46 = 0.3429$

$P(Y=1) = \binom{3}{2} 0.54 \times 0.54 \times 0.46 = 0.4023$

$P(Y=0) = \binom{3}{3} 0.54 \times 0.54 \times 0.54 = 0.1574$

Now

$E(Y) = \sum_{j=0}^{3} j \times P(Y=j) = 1.3803$

Help needed asap! Must be answered using interval notation!

Elina [12.6K]

In this case, we have a colored dot at -1 and a white dot at 3, then the interval notation for that graphed interval will be:

[-1, 3).

<h3>How to write the interval of values in the graph using interval notation?</h3>

First, remember that the symbols ( and ) are used for ends that do not belong to the interval.

For example, if our interval is 1 < x < 2

1 and 2 do not belong to the solution interval, thus, the solution interval is (1, 2).

While [ and ] are used when the ends belong. For example, in:

1 ≤ x ≤ 2

The interval notation is [1, 2]

And in:

1 < x ≤ 2

(1, 2]

And so on.

On the number line, the notation is:

Colored dot: the point belongs to the interval.
White dot: the point does not belong to the interval.

In this case, we have a colored dot at -1 and a white dot at 3, then the interval notation for that graphed interval will be:

[-1, 3).

It took James 5h to paint an 8ft by 24ft wall. At this rate, how long would it take him to paint a 12ft by 36ft wall

olasank [31]

8 * 24 feet = 192 sq feet per 5 hours

12* 36 = 432 square feet

432 is 2.25 times the area of 192 square feet

So, it takes 5 * 2.25 = 11.25 hours
