Answer:
12
Step-by-step explanation:
A 2 - sided counter ; (red, yellow)
A spinner (1,2,3,4,5,6)
Number of trials = 80
P(red and number > 3) :
P(red) = 1/2 ;
P(number >3) : numbers greater Than 3 = (4, 5, 6)
Hence, P(number <3) = 3 /6 = 1/2
Theoretical probability = 1/2 *1/2 = 1/4
Expected number of outcomes :
1/4 * number of trials
1/4 * 80 = 20
Experimental outcome :
Relative frequency = number of outcomes / number of trials
Relative frequency = 2/5
Hence,
2/5 = number of outcomes / 80
Cross multiply :
160 = number of outcomes * 5
Number of outcomes = 160 /5 = 32
Actual outcomes = 32
Difference between actual and expected :
32 - 20 = 12
Answer:
-21 over 24 should be equivalent
Step-by-step explanation:
Equivalent fractions are simple. To find an equivalent fraction simply multiply the denominator AND the numerator by any natural number other than 1 (a natural number is any number greater than zero, numbers that ARE zero or less AREN'T natural numbers i.e. 0, -1, -2, -3, you get the point)
80 x 3 = 240
240 / 5 = 48
