The probabilty that husband and wife will be a live is 30 years from now is 0.6 and 8.0 find the probabilty that in 30 years time a) both will be a live b) nether will be die c) at least one will be a live

Answer:a) 0.48b) 0.08c) 0.44Step-by-step explanation:The probabilty that husband and wife will be a live 30 years from now is 0.6 and 8.0.If probability that husband will be alive 30 years from now is 0.6, then the probability that husband will not be alive 30 years from now is 1 - 0.6 = 0.4If probability that wife will be alive 30 years from now is 0.8, then the probability that wife will not be alive 30 years from now is1-0.8 = 0.2a) probability that both will be a live will be 0.6 × 0.8 = 0.48 b) probability that nether will be aliveis0.4 × 0.2=0.08c) probability that at least one will be alive will beProbability that husband would be alive and wife would die + probability that husband would die and wife would be alive= 0.6×0.2 + 0.4 ×0.8= 0.12+ 0.32 = 0.44
