Twenty students choose a piece of fruit from a list of 4 fruits: apple banana grape and pear. the theoretical probability that a student will choose a banana is. 25. only 1 student chooses a banana how many can the exerpimental probability get closer to the theoretical probability

Significant difference of 0.20

Step-by-step explanation:

No of student = 20

No of fruits available =4

EAch student is independent of the other.

Hence theoretical probability that a student will choose a banana is=1/4=0.25.

But actual experiments showed that only 1 student selected banana out of 20

Experimental probability that a student will choose a banana is.=1/20 =0.05

The difference between the two = 0.25-0.05 = 0.20

Thus there is a significant difference between Experimental probability that a student will choose a banana and theorical probability that a student will choose a banana

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
