Sheila either walks to school or cycles, the probability that she walks it 0.65. if she walks, the probability that shell be iate is 0.4 if she cycles the probability that shell be late is 0.1 work out the probability that on any one day, sheila will not be late for school.

0.705

Step-by-step explanation
