Answer:

The correct answer option is 0.2.

Step-by-step explanation:

We are given that there are 3 red marbles and 3 green marbles in an opaque bag.

If two marbles are chosen one after one without replacement, we are to find the probability of getting both green marbles.

P (1st green marble) = $\frac { 3 } { 6 }$

P (2nd green marble) = $\frac { 2 } { 5 }$

P (both green marbles) = $\frac { 3 } { 6 } \times \frac { 2 } { 5 }$ = 0.2

Answer:

The answer to your question is: letter B) 1/2

Step-by-step explanation:

Data

a = -2

Find the value of expression - 17x-19xpwer4 - 21x power 2,when x=3

Marrrta [24]

Answer:

$-17x - 19x^4 - 21x^2 = -1779$ when $x = 3$

Step-by-step explanation:

Given

$-17x - 19x^4 - 21x^2$

$x = 3$

Required

Solve

Substitute 3 for x in $-17x - 19x^4 - 21x^2$

$-17x - 19x^4 - 21x^2 = -17*3 - 19*3^4 - 21*3^2$

Evaluate all exponents

$-17x - 19x^4 - 21x^2 = -17*3 - 19*81 - 21*9$

$-17x - 19x^4 - 21x^2 = -51 - 1539- 189$

$-17x - 19x^4 - 21x^2 = -1779$
