2x+192=180
-192 -192
2x=-12
/2 /2
x=-6
Step-by-step explanation:
Simple
4x2 = 64
Botg are squares so
2x = 8
x = 8/ 2
= 4
Option C is the correct
Probability helps us to know the chances of an event occurring. The probability of pulling a green or red card is 9 / 100.
<h3>What is Probability?</h3>
Probability helps us to know the chances of an event occurring.
P = ![\dfrac{Desired \ outcomes}{Posiible \ outcomes}](https://tex.z-dn.net/?f=%5Cdfrac%7BDesired%20%5C%20outcomes%7D%7BPosiible%20%5C%20outcomes%7D)
The probabilities of different color cards being pulled are 1/25 for red, 1/20 for green, 1/15 for purple, and 1/10 for black Therefore, the probability of pulling a green or red card is,
Probability = 1/20 + 1/25
= (5 + 4) /100
= 9 / 100
Hence, the probability of pulling a green or red card is 9 / 100.
