Unformatted text preview: P(event)+P(complement)=1 10) The probability of being a twin is 2 out of 90. Write and solve an equation to find the P(not a twin). 11) We want to form a committee to argue to allow dogs at school. If the probably of being picked to be on the committee is 30%, what is the P(not picked)? Experimental Probability= Experimental Probability= Examples 1) A manufacturer decides to inspect 2500 bubble gum wrappers. There are 2450 wrappers that have no defects. Find the probability that a wrapper chosen at random has no defects. 2) James owns a thumbtack manufacturing plant. He produces 8076 thumbtacks a day. If 3% of his thumbtacks are defective, approximately how many defective tacks does he make each day? Homework #____ Homework: p. 214 # 1-20 & 22...
