A jar of alphabet tiles contains 10 unique consonant tiles and 5 unique vowel tiles.

vladimir2022 [97]

Answer: Probability that 3 are consonants and 2 are vowels is 0.3996.

Step-by-step explanation:

Since we have given that

Number of unique consonant tiles = 10

Number of unique vowel tiles = 5

Total number of tiles = 10+5=15

we need to pick 5 tiles randomly,

So, Probability that 3 are consonants and 2 are vowels is given by

$\frac{^{10}C_3\times ^5C_2}{^{15}C_5}\\\\=\frac{\frac{10\times 9\times 8}{3\times 2\times 1}\times \frac{5\times 4}{2\times 1}}{\frac{15\times 14\times 13\times 12\times 11}{5\times 4\times 4\times 3\times 2\times 1}}\\\\=0.3996$

Hence, Probability that 3 are consonants and 2 are vowels is 0.3996.

Solve the following system of equations using elimination: 13x + 5y = 16 2x - 8y = 20

Natalka [10]

13x + 5y = 16
2x - 8y = 20

Multiply the equations;

13x + 5y = 16 [x2]
2x - 8y = 20 [x13]

26x + 20y = 32
26x - 104y = 260

Reverse the signs on one equation;

26x + 20y = 32
-26x + 104y = -260

'-26x' gets cancelled, leaving;

20y = 32
104y = -260

20y + 104y = 124y
32 - 260 = -228

124y = -228

y = -228 / 124

y = -1.84

Substitute in one equation and find 'x'.

Hope this helped! :)
