Year+11+8th+to+11th+August

=8th August: Language: Experiment; Event; Probability; Trial.= In an experiment the probability of an event occurring is estimated by: (the number of times the event occurred) divided by (the total number of trials).

For example: If the experiment is rolling a dice, the event we are interested in could be getting a 6, the probability of getting a 6 is theoretically 1/6. A trial would be to roll the dice. If we rolled the dice 30 times we would expect to roll a six 5 times. Imagine we rolled a 6 15 times! The probability (based on the results of our experiment) of getting a 6 would be 15/30, which can be expressed as 0.5, 50% or 1/2. Clearly the dice is not a fair dice! []

=9th August= Tree Diagrams on the white board, and page 144 to 146 of Fast Track. 155 to 157 of on track

=10th August= Fast Track : By the end of today pages 141 to 147 should be completed. By the end of today ON TRACK pages 148 and 149 should be completed. Make sure you know the term Sample space, and know what a venn Diagram is.
