Step-by-step explanation:First, you can plug in the numbers, so the equation would look like 126=1/2b(18). Since theres 1/2, 1/2 of 18 is 9, so it would be 126=9b. 126/9=14
Answer:
5/9
Step-by-step explanation:
Let the total number of buttons is x.
- Round buttons = 80% of x = 0.8x
- Square buttons = 0.2x
<u>Number of red buttons:</u>
- 0.1*0.8x + 0.5*0.2x =
- 0.08x + 0.1x =
- 0.18x
Number of red square buttons is 0.1x
<u>Required probability:</u>
- P = 0.1x/0.18x = 10/18 = 5/9
