Probability

 L.I to work out chance


This week for maths we learnt about probability, probability is the chance of something happening. To expand our knowledge we made a DLO about one of the questions we did and explain how we worked it out. The question that we solved was about the chance that a person could pick the same two flowers out of a bag, there were 6 frangipani and 4 tiare taina that made the chances of her pulling a frangipani 6/10 and the chances of her pulling out a tiare taina 4/10. When she picked a second time the chances would be the same (6/10 for frangipani and 4/10 for tiare taina) After we have done that we multiply the chances to get the answers, first you multiply 6/10 by 6/10 (the chances of pulling two frangipani's) The answer we get is 36/100. After that we multiply 4/10 by 6/10 (the chances of pulling a tiare taina and frangipani) Then we multiply 6/10 by 4/10 (the chances of pulling a frangipani and a tiare taina) Lastly you multiply 4/10 by 4/10 (the chances of pulling two frangipani's) Finally we add 36/100 and 16/100 ( the chances that two of the same flowers are pulled) Which gives us 52/100.
