9/38 x 9 /38 =81/144 both of the events are indepent
Alisiya [41]3 years ago
4 0

Answer:  

The correct option is D. 9/38x9/38 =81/1444

Step-by-step explanation:

Total number of marbles in the bag = 38

Number of white marbles in the bag = 14

Number of gray marbles in the bag = 9

Number of blue marbles in the bag = 15

We need to find the probability that Jane takes out a gray marble in both draws

\text{Probability that Jane draws gray marble in first draw = }\frac{9}{38}

Given that : Then Jane replaces the marble for the second draw

\text{Probability that Jane draws gray marble in second draw = }\frac{9}{38}

\text{Probability that Jane draws gray marble in both draws = }\frac{9}{38}\times \frac{9}{38}

\text{Probability that Jane draws gray marble in both draws = }\frac{81}{1444}

Therefore, The correct option is D. 9/38x9/38 =81/1444

Need help so confused thankssss

Let complementary angle be x,

Then the other angle is 4x

x + 4x = 90 ( complementary angles)

5x = 90

x = 90/5

x = 18,

The measure of the smaller angle = 18

And the measure of the larger angle = 4x

= 4 * 18

= 72

The supplementary of the larger angle is,

Let y be the other supplementary angle.


72 + y = 180 ( Supplementary angles)

y = 180 - 72

y = 108.

Hence, the other supplementary angle is 108 degrees.


Hope you understood. Plzzz let me know if you have any doubts.
