The total number of marbles in the bag is 1 + 4 + 3 = 8
The probability of drawing one marble and getting blue is 4/8 = 1/2
Since marble is put back and he draws again, the probability will again be 1/2
The total probability = 1/2 * 1/2 = 1/4.
1/4 <<<<Answer
Answer:
x=2
Step-by-step explanation:
7(5+2x)+x=65
35+14x+x=65
35+15x=65
15x=65-35
15x=30/15
x=2
Answer:
x+4
x+1-2=x-1
Step-by-step explanation:
x+4/x-1=11/16 x should be different than 1 cz 1-1=0
16(x+4)=11(x-1)
16x+64=11x-11
16x-11x=-11-64
5x=-75
x=-15
...42, -193.. thats the 4th and 5th Hope this helps
