Answer:

Answer: <em>4a - 5 = 10 - a </em>

Answer: <em>4a - 5 = 10 - a <=> 4a + a = 10 + 5 ( chuyển vế đổi dấu, số 1 vế biến 1 vế) </em>

Answer: <em>4a - 5 = 10 - a <=> 4a + a = 10 + 5 ( chuyển vế đổi dấu, số 1 vế biến 1 vế) <=> 5a = 15 ( a đi 1 mình nghĩa là 1a) </em>

A gumball machine has just been filled with 50 black, 150 white, 100 red and 100 yellow gum balls that have been thoroughly mixe
Andrew [12]
<span>Exactly 33/532, or about 6.2% This is a conditional probability, So what we're looking for is the probability of 2 gumballs being selected both being red. So let's pick the first gumball. There is a total of 50+150+100+100 = 400 gumballs in the machine. Of them, 100 of the gumballs are red. So there's a 100/400 = 1/4 probability of the 1st gumball selected being red. Now there's only 399 gumballs in the machine and the probability of selecting another red one is 99/399 = 33/133. So the combined probability of both of the 1st 2 gumballs being red is 1/4 * 33/133 = 33/532, or about 0.062030075 = 6.2%</span>
