3 blue + 3 yellow = 6 total marbles.
The probability of picking a blue one first would be 3/6 ( 3 blue out of 6 total marbles).
3/6 reduces to 1/2.
After picking the first marble, there would be 5 marbles left in the bag.
The probability of picking a yellow one would be 3/5 ( 3 yellow and 5 total marbles left).
The probability of picking a blue then a yellow then becomes:
1/2 x 3/5 = 3/10 = 0.30 = 30%
Answer:
$90.38
Step-by-step explanation:
25% of $120.50 is $30.125
$120.50 - $30.125 = $90.375 rounded to $90.38

Answer:
18.4%
Step-by-step explanation:
The formula for rel. freq. is:
Relative Frequency = Class Frequency/n
Where
Class Frequency will be the number of students in the class we are interested in (in 35-38, the number of students is 9)
n is the total number of students [which is 6+7+8+9+10+9= 49]
Putting into formula we get:
Relative Frequency = 9/49 = 0.1837
To get percentage, we need to multiply by 100:
0.1837 * 100 = 18.37%
Rounded to 1 decimal place, that is 18.4%
