A box contains identical balls of which 12 are red, 18 white and 8 blue. Three balls are drawn from the box one after the other
svet-max [94.6K]

Answer:

a) 12/323

b) 8/233

Explanation:

a) The probability of a red ball being drawn is 12/38, or in a simplified fraction, 6/19. To find the probability that 3 are red you would multiply the probability of the fraction for each, except subtracting one from the total each time as the drawn is done without replacement. This is done as follows: 6/19 × 6/18 × 6/17= 12/323

b) The probability of drawing a blue ball is 8/38, or 4/19. To find that the first one is blue and the rest are red, the equation is done as follows: 4/19 × 6/18 × 6/17 = 8/233

(hopefully I did this right)

What is it with the name Sara these days!? XD
Komok [63]

66 mph

Explanation:

Average speed is the rate of change of distance with time:

       Average speed = \frac{Distance }{time}

Given parameters:

Starting point = 88mile marker

End of journey = 121mile marker

time = 30minutes = 0.5hr(60min = 1hr)

Solution:

The distance covered in this journey:

  Distance = End of journey - starting point = 121 mile - 88 mile = 33mile

 Average speed = \frac{33miles}{0.5hr}

                            = 66mph

The average speed of Sara's mum is 66mph
