Pavel [41]

Answer:

0.2239

Step-by-step explanation:

Given that you have two hats. In one hat are balls numbered 1 through 15. In the other hat are balls numbered 16 through 25. I first choose a hat, then from that hat, I choose 3 balls, without replacing the balls between selections.

Either I or II hat can be selected.

Prob of selecting any one hat = 0.5

After selecting I hat, selecting 3 balls can be done in 15C3 ways and from II hat it can be done in 10C3 ways.

total no of ways of selecting 3 balls = (10+15)C3 = 2300

Probability required $=\frac{0.5*15C3+0.5*10C3}{2300} \\=\frac{455+60}{2300} \\=0.2239$

To open a safe five numbers must be entered on a keypad. The keypad contains numbers 0-9. The numbers have to be entered in a ce

IgorLugansk [536]

Answer:

30.2%

Step-by-step explanation:

a. For each slot there are 10 possible numbers (0-9). Since there are no restrictions, the number in each slot is independent of the other. We can calculate the total number of possibilities using the product rule.

N = 10 × 10 × 10 × 10 × 10 = 10⁵

b. For the first slot, there are 10 possibilities.

For the second slot, we cannot repeat the number that we used in the first slot, so there are 9 possibilities.

For the third slot, we cannot repeat any of the previous numbers, so there are 8 possibilities.

For the fourth slot, we cannot repeat any of the previous numbers, so there are 7 possibilities.

For the fifth slot, we cannot repeat any of the previous numbers, so there are 6 possibilities.

The total number of combinations without any repetitions are:

10 × 9 × 8 × 7 × 6 = 30,240

c. The probability that the safe's five numbers do not repeat is:

P = favorable outcomes / possible outcomes

P = 30,240 / 10⁵ = 30.2%

Four times a number plus five times the number is the same as ten more than eight

salantis [7]

Answer:

The number is 10.

Step-by-step explanation:

Given that:

Four times a number plus five times the number is the same as ten more than eight times the number.

Let,

x represent the number.

According to given statement,

4 times the number + 5 times the number = 10 + eight times the number

4x+5x=10+8x

Solving the equation,

9x=10+8x

Subtracting 8x from both sides

9x-8x=10+8x-8x

x=10

Hence,

The number is 10.
