The highest mark in the Science test was 92. Three students scored 46 which was 6 marks higher than the
lowest score. What was the range of the scores?

52

Step-by-step explanation: if 46 is 6marks higher than the lowest mark then, the lowest mark is 40

range = highest value-lowest value

so, 92-40=52

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
