Will need to use tinspire in some question to solve . need explaiantion for the answers and how you did it. check anwers on last page.
Task 2
Assignment in probability calculus
For a particular game, the outcomes are red, green, yellow and blue. The probabilities appear from
the table below.
| outcome | Red | Green | Yellow | blue |
| probabilty | 0.3 | 0.2 | 0.1 |
a) Determine the probability of blue
The game is played 2 times.
b) Explain that the probability of getting green both times is 0.04.
Task 3
Assignment in probability calculus
Sanne rolls 2 dice.
a) What is the probability that the dice show the same?
Per draws one card from a regular deck of playing cards (52 cards).
b) What is the probability that he draws a red face card (pawn, queen or king)?
Task 4
In a game, a yellow and a red die are thrown and the product of the two eye numbers is noted.
If, for example, the yellow die shows 3 and the red die shows 2, then the outcome of the game is 3 ยท 2 = 6.
The table below shows an incomplete list of the possible outcomes.
a) Complete a table with all the possible outcomes.
b) Determine the probability that the outcome will be 10 or 12.
Tip: In TI-Nspire you can write the table in the matrix template.
Task 5
